It doesn't sound like your immediate family is the most healthy representation of type either, though, from what I'm heard (although I'm not too sure on that, since obviously I don't know them that well).
Dad: ISTJ
Mom: ESFJ (not too sure this though)
Not a problem at all.mf, what's your Dad like? If you don't mind me asking?
I think my Dad is the same type and would like to see if their are similarities.
