Being talkative

Hi,MyLotters! A new friend of mine said that when she first met me she thought I was very quiet and reserved because I tend to be silent in front of strangers because I'm shy.But then,according to her, after she got to know me she discovered that I was an unstoppable chatter box.She,on the other hand, also talks nonstop but she is very social and I believe she never felt shy in her entire life.So,my question is what kind of person are you?Are social,talkative,shy,silent...Do you behave differently in front of friends and strangers and do you behave online the same way (conversation wise) as you would face to face with the people you talk to?And are there days in which you feel more like talking to everyone and days in which you'd rather not say a single word?
