Thanksgiving is quickly approaching.  Within every family and every group of friends, there can be a person or two who we may deem extremely negative.  How do you cope with negativity and people who, maybe unknowingly, can drain the fun and joy out of a festive occasion?

I enjoy saying a little prayer prior to an event when I know it will be challenging.  Plus, I like to look to the bible to help cope with the stress I feel after a negative encounter.  Does anyone know of any good advice, bible verses, a great prayer, or words of wisdom to help combat negativity?
