Good point. I guess anything more than saying a simple "I don't know if it will work for you, but *such and such thing* works for me" would be considered prying.Sometimes it annoys me when people try to pry too deep when I don't want to talk.
I'm really private IRL, directly trying to talk to me about anything too personal may have me running for the hills! Your ISFP friend may be be the same.Let's say the ISFP doesn't want to accept any help, but you know he needs it. Do I go all Fi at him like Vader, "search your feelings, you know it to be true"?
