Not everyone is doing Thanksgiving today.
I just got a reply to a new user tips email we send out. It's triggered by having your account for seven days. He's mad that we emailed him on Thanksgiving. I thanked him for his feedback and told him we're a Canadian company with a wide international audience, so our office and many of our users aren't celebrating Thanksgiving today. Also, the email he got just happened to come today. Had he started his account one day earlier, he would have gotten it yesterday.
If you want to have a love affair with this holiday, have fun. But don't give me shit for doing my job on a holiday I'm not a part of. The world doesn't stop turning just because it's Thanksgiving in America.
