Probably not considered a disaster to most, but for me it was.
I woke up extra early to get started on Thanksgiving lunch for my DH's family that was in town for Thanksgiving. I also had to cook a giant bird for my family that we would be eating at in the afternoon. I slaved in my kitchen for HOURS! All by myself making potatoes, broccoli casserole, green beans, corn pudding, rolls from scratch, pie, dressing, gravy, cranberries and turkey. I got out all of my nice dishes and made a beautiful table setting.
We sat down to eat any everyone said they weren't really hungry.

Not hungry? You haven't eaten breakfast yet! They each made tiny plates, left food still on their plates and then pulled out a store bought pie my DMIL brought down with her to eat for dessert. Not one thank you or acknowledgement of anything tasting yummy. I made up some reason to leave and got in my car and drove to my moms where I lost it and cried like a baby. I had never felt so unappreciated in my life. When I got back I finished up my other Turkey which DH and I took to my grandparents where everyone said how juicy and tasty it was.
I learned my lesson. I no longer slave over a meal for my in-laws. We go out to eat on Thanksgiving.
