I don't know if anybody has ever given me a nasty look, I try not to look people in the eye unless they are coming right at me. That being said before I get out of the car I look in the mirror and tell myself, Lets give em something to talk about.
I think you know you will get the looks and the giggles from your post. My advise is to get back out as soon as possible so you get back into your comfort zone.
Best of luck
