Small Talk

I envy people who are good at small talk. I suck at small talk. When I bump into someone I know pretty well at the store or something it's incredibly awkward and I don't know what to say. 

However, usually they are really good at small talk and carry the conversation and at the end it was satisfying. This skill is so beneficial to have around people you don't really know or people you do know but you aren't in environment that you typically see them at.
