Oil and Water

I am listening to Foreskin's Lament while I pack and there have been so many great quotes but not having the actual paper book in my hands is causing me to quickly forget all of them. So I paused it and ran over here to type this gem:

My family and I are like oil and water...if oil made water depressed and angry and want to kill itself.

This is not necessarily true for me and MY family (although they make me want to pull my hair out sometimes), but an argument can be made for this describing my relationship with certain "other" people's parents...
