My husband is great, too. But of course there are minor irritations that I don't even mention to him. Like...
1) He thinks he is SOOOO funny, and uses the same "lines" over and over and over. For instance, I'll ask someone else in the room a question like "do you want jelly on your toast?" and it's obvious I'm asking our son because he's standing right there, and DH will say "No, thanks, plain is fine". Or even "did you have a good day?" to our son, and DH will say "Mostly". He says "Viola!" instead of "Voila!". Every. Single. Time.... When I place his laundry, folded on his side of the bed, he says "Thanks for starting my laundry". And there are other "jokes" and funnyisms that he uses ALL THE TIME, which would be endearing if used SOMETIMES, but it's EVERY DAY....
2) Sometimes when I ask him a question, instead of answering "yes" or "yes, please" he will say "OK!" - and it just drives me crazy. Like - "Would you like some tea?" - DH - "OK!". Or "I'm getting some coffee, would you like a refill?" - DH - "OK!" That's totally stupid, but it does grate on my nerves.
3) and speaking of men and their long, drawn out bathroom habits. He sits SO LONG that his legs go to sleep. Then he gets up and limps around like he's about to fall, hanging on to the wall and furniture. I SWEAR that he's playing it up. Why sit so long? If it isn't ready to come out, get up and walk around and do something else for awhile.
