I'm of two minds about ISFJs, to be honest.
On the one hand, I got burned pretty badly by my ISFJ ex (who I realize was definitely not the healthiest example of her type) -- our relationship went more or less like this. On the other hand, though, judging from the responses to this thread, it seems like healthy ISFJs are wonderful people. (I don't personally know any, besides the ex, of all the friends and family whose types I've confirmed.)
I'd love to meet a nice, healthy ISFJ girl who can help me keep my shit together while also finding my whole "absent-minded professor" routine cute.
