My significant other annoys me because... when i am moaning or nagging or going on about something (as I do) he goes "what are you going on about woman??"
he's untidy
he has a bad memory
he thinks things are funny when actually they are inappropriate
he will eat all the cookies or crackers or whatever all at once so there won't be any for later
sometimes he yells instead of speaking normally and doesn't realize it is too loud
