Yeah I started feeling left out at my job when the others were down the other end chatting away, couldn't be helped though I had to stay down the other end to serve customers. Still made me feel left out, the thing that really makes me feel left out is that I don't know what to say when conversations arise. I might as well be a fly on the wall.
Hang in there dude, you haven't been there too long, and I think you're just too aware of being shy, it's like being frozen in one spot while life revolves around you, at least you've got a good job and I bet the pays great too.
So what are you working as?
