Caseysmom, I hope you have a stress-free Thanksgiving with your sister and all the others. Please tell me she didn't really ask you to bring mashed potatoes for 23 people. If she did, I hope you ordered them from a restaurant!
I like Thanksgiving because it's a relatively low-key holiday for my very dysfunctional family. A nice meal, no gifts, and it's okay to only stay a few hours because of having to work the weekend.
