Wanted to give a quick tip to you all for really looking people in the eye without looking odd or thinking too much about it. It's all in the face, as long as you don't have a dead look on your face it will all be ok. I've noticed that when my face goes blank, so does my mind and I start thinking too much about what to say. Slightly smile (with your tongue pressed against the back of your front teeth to relieve tension) , be humming to yourself, even chewing gum, anything that keeps you from looking emotionless and you'll be able to have more fun expressing yourself and less like you're being judged by everyone else.
