You know what's funny, I didn't think anything my boyfriend did annoyed me.....until we moved in together!  We've been in our house for a week now, and I am learning so much about him.  I just realized that whenever he has nothing to do and is bored, he whistles (that spelling looks really funny).  It drives me crazy, but I haven't said anything and I am learning to adapt.  I guess that's part of the compromise of moving in together!  
I'm sure I do things to annoy him as well.  However, he never brings stuff like that up.  He just deals with it!
