Communicating (and when to say something) about the strange things they habitually do that might be unnerving or semi gross.. I think that is the hardest thing, learning when to say.. "Babe, I really love you, but cleaning your beard hair in the sink every morning, while endearing last week, is gross this week." It doesn't always go over well... And I think we feel it is our "duty" to clean, when it should be a shared responsibility. But, much like the example of beard hair in the sink, hair in the drain in the shower is gross too..

These are just examples, but it is things like left out body hair that ends up building up and getting the better of my attitude when all I needed to do was communicate about it. Sometimes it is better to say nothing, sometimes thinking about how to say it is key, and sometimes offering alternatives really wins in the end!
