Full disclosure: I'm a suspected/self-diagnosed Aspie, so my opinion may not officially count.
That being said, I think it's VERY normal to sometimes feel awkward in certain situations.
The reason *I* suspect myself of Asperger's is that I NORMALLY feel socially awkward. Even things like "Hi", "How are you?", making eye contact while talking, and groups of 2+ people are very confusing and sometimes scary for me. Often, when someone looks in my eyes, I feel like I'm being stared down and intimidated, especially if they're waiting for a response from me and I'm freezing up.
But some social awkwardness is normal, I believe.
