What do YOU do that annoys your spouse?

Nothing

I leave my purse on the credenza by the front door and I know this drives him crazy. I really do try to put it away at the end of the day but it is a hard habit to break.

It also drives him nuts that I don't drop everything to answer the landline.

I know there are others, but those are the first two that came to mind.

This is totally us!  A 1-2 second pause, fine.  I can wait.  But anything longer is just an invitation for me, lol.  

I am a blanket hog. We have started using two blankets at night and it has really improved our sleeping experiences! I also keep my feet on his lap when we watch tv and move them around until he gets the hint that I want a foot rub. He says I should just ask him instead of playing games.

blow jobs...... oh yeah that is what I DON'T DO that annoyed him to go find it else where. 

That I keep putting his stuff away, where it actually belongs, imagine that. So, when he goes to look for his screwdriver (insert any tool here) on the coffee table, it's actually IN HIS TOOLBOX. Goes for all kinds of other stuff he leaves around the house. Drives me nuts. Me putting it away, drives him nuts. And so it goes......

I talk a lot which interrupts his favorite past time of watching TV, he doesn't like my driving and I sometimes get really angry about things he thinks is unimportant (which of course just makes me angrier).

He probably doesn't like that I nag him about doing things around the house but if he would do them the first 10 times I ask the problem would be solved so that's on him.

Seems like most things...in particular anything that drags him off the couch. Last night was asking for the dog to be taken out

When I lift something too heavy. When I stand on a chair to do something high up.

He does not want to have to call 911.

I don't mean to be, but I'm a terrible passenger seat driver. I do make an effort to not slam on the imaginary brake pedal on that side, but sometimes it just happens. It drives him crazy.

I'm a backseat driver with him.

And I never want to pick where we go out to dinner.

ditto..or I just talk right over him

I hang my damp bath towel on the post at the end of the bed.

My excuses are: I have to use the kids bathroom to take a bath because our bathroom only has a shower, the towel rack in our bathroom is full because DH hangs his clothes he's going to wear again on there, and I can't get our bathroom door open all the way because DH's dirty laundry pile on the floor is behind the door. DH hangs his wet towel over the top of the shower so you have to move it to get the shower door open so he's not totally innocent...

So yes my damp towel hanging on the post at the end of our bed is his fault, if he'd just use a hamper like a normal person the problem would go away

There are plenty more but I don't feel like writing an entire novel.

I'm sure lots of things, but those that immediately come to mind:

Eat loud stuff like chips or Corn Nuts when he's not also eating them. 
Used to give away/dispose of stuff he never uses (I don't do that one anymore though).
Leave mail piled up on the kitchen counter (but in my defense, it's HIS mail that he never looks through).
I like silly stuff that he thinks is dumb, like Mickey Mouse memorabilia or Muppet wall decals.
I don't come up with suggestions for what/where to eat, mostly because I don't care.
He thinks I go too over the top on holidays and birthdays. (Okay, maybe the year I hid 150 candy filled eggs for Easter was a BIT excessive...)

ETA: **GypsyGirl** reminded me that he thinks I add too many details to a story or joke. He too wants everyone to get right to the point without adding any of the pertinent facts. But yet when he's telling the "story" about the 9' sailfish in our livingroom (which is a total fabrication because he bought it off of a client's garage sale, LOL) I'm supposed to just let that one go!   Yeah, whatever!
