You Make a Good First Impression
You probably are making a much better impression than you realize.
Social situations can be a bit awkward for you at times, and you tend to over think what you say and do.
If you make a social faux pas, you remember it a lot longer than anyone else does.
Just relax and do your best. There are little things you can do to improve your social image.
Express more of an interest in the people around you, and be a good listener.
The secret of fascinating people is that they find everyone else fascinating!
I know I'm quite shy when I'm with strangers and honestly, I'm not the best listener around. Have to make some change, I guess! :P
