Do you get along with the in-laws?

There are so many jokes about the dreaded in-laws, but in all my relationships I have always been very close in my exes families. In fact, I still keep in touch with the mother of an ex from high school! We tell eachother I love you still and she came to see me the last time I was in the hospital.

I mean, I know there are things that can get annoying… Especially if they are your neighbors… (My sister is in that situation.) But are they really that bad most of the time?
