Libra potential to act diva

I find that most of my friends do not have this attitude and they are very open to meeting strangers and talking to them, in fact they seek it out.

This is in contrast to me who has a diva behaviour. The few words I say to a stranger is "excuse me", "I don't work here", "thank you" and the occasional "hello". In fact, I say very little to strangers in front of my face but my friends have no problem with having long conversations with them and being friendly right from the start. I am starting to feel that I am holding them back or something.

I am wondering if this is normal for a Libra, cause it is only Libras who say anything nice about my "diva" behaviour, including totally ignoring people selling credit cards.
