I was just told that I had no enthusiasm in the way I approached people. Most people probably would have taken offense- I was a little caught off guard tbh- but I'm glad I was told this because it put things into perspective for me.
I don't spend much time around others, so I get nervous easily and I have weird reactions. I can be amicable in short term contacts, but, I've noticed, when I'm around someone for a long time that I'm nervous around I get really cold in temperament.
So I took this to heart. I'm glad someone had the balls to say this to me. I don't want people to think of me that way, I want to befriend others easily, so now that I know this, I can work on changing myself to be more amicable.
(most people would probably change out of anxiety, I think; I do it because developing communication skills has become a hobby of mine, since I've come out of my several year's exile from society)
