Starbucks

Every Friday afternoon I pick Carlos up from work at Chinook Mall. My weekly routine is to get to the mall ten minutes early, run into the mall and get a grande non-fat, sugar-free, vanilla tea misto with grean tea. Every time I go there the same people are working, and they are having so much fun together. I look at them and I envy them, singing and talking and charming every single customer. At the same time that I envy them I feel uncomfortable. It bothers me that I feel uncomfortable, I avoid eye contact I feel awkward if they try and charm me, it's not like they are trying to "pick me up" they are simply being nice to their customers.

Why does it make me feel so uncomfortable??
