I am a straight forward yet shy guy..i am telling so because a can't be familiar with anybody from my side. Some time it happens as i feel the person is not that important but some time sadly due to my personal disability of talking in English i can't be familiar. The main reason is my vocabulary. Although my style of talking is good but many a times i stammer as i could not search the proper word in my mind, and there everything stop. I found it humiliating and insulting for me. I think if my vocabulary will be strong than i can easily get back my shelf confidence.
