Yeah, there were certainly ground-rules established ahead of time, and we wouldn't have even considered it if we didn't have a pretty excellent relationship.

It's been ~18 months so far and things are still going great. I really don't know what we would have done without the extra help just a phone call away...

I love living 5 minutes away from my parents. We are close enough we see each other frequently, drop by to do favors, borrow tools, carpool to events, etc., but there is juuuust enough friction to getting to the others house it doesn't feel as if we are living together / I'm still living at home.
