Today at work, a coworker mentioned that he had multiple invitations to Thanksgiving dinners at various people's homes, and had to choose which invitations to accept. He's going to one on Sunday and another one on Monday. I will be home alone for Thanksgiving. I didn't feel particularly sad about it until today. No one has invited me anywhere, and there's no one I could invite to spend the day with me. My existence matters so little to anyone.
