What are some comments you'd love to make to LL partner but don't?

Sometimes the resentment pops up and my mind wants to snap back with a response but I bite my tongue to retain the peace.

For example, I prefer to wash my dishes by hand even though my house has a dishwasher. When she sees me doing it, she always says "you know you have a dishwasher, right?" It's all I can do to fight the urge to say "yeah, well I have a dick I don't use either".

In the spring I had to take her to urgent care. On prelim questions they asked if she was sexually active and she said yes. All I really wanted to ask was "with who?"

Talking to her cousin about the 'oops baby' our neighbors had, she said "yeah, that's not gonna happen because he and I are both fixed". Bit my tongue and didn't say "not like it would make any difference if we weren't".

I'm sure others have your situations like these, what are they? Could be a good read.
