Tips on getting through an event with someone you detest....

Make it a game and reward yourself with something if you can get through it. Kind of want to know the situation though.

I wish I knew. I'll be in the same boat on the 24th.

Pretend you are Kate Middleton with the press watching your every move and just be absolutely charming.

Or, just nod politely and say "Interesting" or other platitude. You're probably not the only one who knows/thinks the person is lying. You don't have to give any credibility to their statements by engaging further than that.

Then come back here and tell us all about it.

I have about 10 lipsticks in my purse. I adjust my lipstick every time there is a lull in the store. You could make excuses to go put on lipstick, powder your nose, pee, get something to drink, smoke (I know it sounds terrible but hey there are still people who smoke so I am not excluding them), anything to get away from her/him.

Just tell yourself that this person either has a mental illness or very low self esteem and either way it has no impact on the truth as you know it to be. If you see what she/he is doing then chances are high that others do too.

And ice. Lots of ice chewing. Take it out on the ice.

I think you should not try to censor yourself...just let it fly. Tell them what a jerk they are AND THEN come right back here and tell us all about the explosion

We can tell you what snide remarks and cheap shots to take at him/her. We are the Peas...we will post pictures of the Hoff and the Drama Llama for you to laugh out loud at so just when things get really bad we will have the Drama Llama show up or something.

Or how about the Giraffe from Geico? Mike, Mike, Mike, Mike, Mike what day is it? Oh heck we can have some fun with you...

Two things: first, I recently found out that several people who I thought were fooled by XMIL little miss perfect act were in fact not fooled, just polite. That cheered me way beyond reason, it was just so good to know that others DID see how two faced she is.

The other: call it karma, call it reaping what you sow, either way, she'll get hers eventually.

Imagine a superhero mask on your face, your superpower is being civil.

If I can live with XDIL for 13 years, you can make it through this event.

Oh,  and you have a cheering section, too. (Us)

My friend gave me this slightly strange tip and it works - for me - to vent a little frustration without being vocal..... Under the table (hidden) give her the finger! Sounds bizarre and juvenile I'm sure but somehow it helps a bit.

How many people in your group? Do you have to sit right next this person? If not sit as far from them as you can. You may have to be at the same table, but no one says you have to talk or engage with them. Yes, they will talk about how perfect they are, but you know better and can just let her talk. As others have said, she is not fooling near as many people as she thinks.

Also, I try to figure out what is happening in a person's life that they feel the need to make so much up. I try to feel for them, if and when I get to that point, I actually can start feeling sorry for them.

Start a thread here and tell us everything you want to tell her?

Do NOT speak or respond to this person.
As others mentioned, pretend the news will feature your reaction, reward yourself for good behavior later.

If you sit silent, the table dynamics will change. Do not engage in a challenge as you will be regarded as the rude one. Just let it pass. ...hard to do, but you can do it if you set your mind to it.

Take the high road. If you must attend this event, then smile and make polite but meaningless social conversation if and when you can't avoid interaction with this person. Pay attention to the event activities, focus on the other people at your table, or the food if there is a meal, use you phone to distract yoursekf if necessary, and behave. There is no reason why you cannot stay the course without causing embarrassment to yourself or those around you. If this person targets you or willfully starts something unpleasant DIRECTED AT YOU PERSONALLY, gather up your stuff and say "I will not allow you to ruin my evening, good night"- calmly and politely, and leave the table. Be the bigger person and don't give them the power to make you lose it in front of the entire table. If you do, this will give them exactly what they want. And don't feel like you must be the one to call her out on anything. This event is not the place. All that will do is give the people who witness it lots to talk about.

And like a previous poster mentioned, if you honestly believe that you will not be able to control yourself in a public venue because you no longer have a "filter" then there is more going on here....

Good luck!
