Shy.

Sometimes some random thought just hits me and then for some reason I think it's novel and stick to it or at least try it out until I get bored. So for example I just decided I feel especially more than normal shy this week. Maybe I'm just tired? I guess I'll be staying indoors with my laptop and be studious :)

I like the biological explanation of "shyness" in Wiki which was "tends to avoid human beings".

Shy sounds a whole lot nicer and more acceptable than "socially avoidant"...

Trust me if I had a choice in my nature I would have chosen to be an Extrovert-HANDS DOWN!

But for now *shy* says bye!
