Long story short, two nights ago a female highschool friend of mine that I haven't seen in 25 years came over to my house. We are both divorced. We were sitting on the couch I was on one end she the other, talking about the usual things, work, kids old school friends and such but every so often while talking she would lean in and pat me on the leg. Now I've had other women do this while talking, usually on the arm and since I'm terrible at taking hints, I was wondering does this really mean anything or is this just a habit that some people have. I have never been the touchy feely type and have always been hesitant about "invading peoples personal space" when around someone that I don't know or have just met. What's your opinion?
