My husband is ENTP. I push him ahead of me whenever we are forced into a new social setting. He makes me laugh - all the time. We are pretty much on the same page about how to raise our kids. In some ways he frustrates the hell out of me, probably because we are too much alike (neither one of us remembers to pay the bills.)
My closest friend is INFJ... she's complex, sweet, trusting, fun and loyal. She encourages and inspires me. She's also a little on the wacko side (believes in UFOs and psychic abilities).
EDIT: I have another close friend who I would type as ESTP... she is resourceful (I swear - she can make money out of thin air) and fun to be with, her business sensibilities (entrepreneurial instincts) are awe-inspiring, she wears me out with her energy - I can't keep up with her need to go, go, go. We were practically inseparable last summer, but I think the friendship kind of ran it's course... she tends to fly solo, her mother said she rarely spends as much time with someone else as the time her and I spent together last summer. We connected on a deep level, I don't know what exactly it was... perhaps the mutual T and P strengths?
