I'm quite different from my INFP cousin, and even though close, we have many clashes with each other. This usually results from her trying to "help", and me refusing, as I rather take time out to deal with it myself. I read that INFPs tend to reach out for people even though they don't ask for it, and when people don't accept their helps, it hurts their feelings. She's dreamier and creative. We both love to draw, but her arts are much more abstract, consisting of angels, saints, masks, trees growing from hearts, etc. Mine are just people posing and smiling.
And do ISFPs necessarily need to be good at arts and craft?
