Wait for all of the thankyous to pour in
Sure, you've done a horrible, horrible thing this Thanksgiving, but the important thing is that everyone is still alive (unless grandma twerked herself to death), and pretty soon they are going to realize just how dangerously close to death they came. With this realization will come a truly authentic feeling of relief that their lives were spared in this horrific ordeal, and they will be THANKFUL for remaining alive. Way to go! You just taught everyone the true meaning of Thanksgiving. Now just wait until Christmas!
