Perfect INFJ first date???

I'm not a lady, but I'll give some advice from an INFJ type of person. The only thing I can think of (seeing your type) that stands out is that "P"... oh that cured "P"! The best advice I can give when you're dealing with any INFJ is to... follow through. It doesn't matter so much what you do or where you go, just make sure you see it through to the end. It doesn't matter what it is you see through to the end, just tie it up neatly for them.

Don't leave things ambiguous, if you value her sanity that is. If it goes well, make sure you let her know. If it ends badly, let her know. The last thing you want is for an INFJ to start using their Ni against you. You know, that voice we get in our heads that occupies all of our free time with things like, "I wonder if they meant this, or if they really meant that? Why didn't they say this to me, but they did say this instead?"

It's going to happen regardless of what you do or don't do, but don't let it escalate out of control!
