Here's a tip I repeat every year...
I can tell from spending time with my clients and friends  recently, that many people are heading to Thanksgiving gatherings with some  ambivalence. Families are "messy" and if you will be spending time  with yours, you too may see it as a mixed blessing.
So here's my tip for you...if someone slights you, makes a condescending  comment
, tries to impress you with their success, brags about their  "perfect" kids, drinks too much and gets "loose lips," gets  their feelings hurt, or in any other way makes you feel uncomfortable, say to  yourself, SO WHAT! 
Really, so what...these scenes are being repeated in homes across the country.  You've been annoyed, offended, pissed off, or hurt on other like occasions. How  about trying something new and just let it go? Choose not to have negative  emotions, let people get on your nerves, or be critical. Recognize that these  are patterns that have been in place for years. Know that no family is perfect.  So what that yours isn't either! Enjoy them for who they are.
The holiday is about giving thanks. If you enjoy yourself in spite of the  idiosyncrasies of the people you've spent it with, you can give thanks to  yourself  for being an adult, being human, and cutting you and others some  slack! 
Happy Thanksgiving!
