Re: Approach. Stay there. Don't move.
Ahh, I remember when I had this problem. It's now minor and I'm rapidly improving on it. All it requires is:
A. Lots of conversation
B. Lots of studying
The more you talk, the easier you discover it is to just go with the flow when you are in front of someone. Being autistic, it was an extremely difficult problem for me to just maintain a random one-on-one conversation. Now, it isn't as hard, and I get more enjoyment out of it. However, I have my occasional moments where I still have trouble. My usual problem is when the person I'm talking to becomes distracted by something else. I feel that in time, this problem will go away too
As for studying, check out the videos on youtubes. Sasha Daygame is a favorite of mine. As for books, check out How to Make People Like You in 90 Seconds or Less.
