What time to you eat Thanksgiving dinner?

We usually gather around noon, start eating by one or two and then napping in front of the TV by three or four.

Honestly, I've never even considered some people do Thanksgiving for dinner time. Of course I've heard the phrase Thanksgiving Dinner before, but that always meant the proper coordinating of courses in my head than any sort of indication of timeframe. Above is what we do, what we've always done... I just can't fathom waiting until after 6pm to eat all that food. What do you even eat for lunch on such a day? Anything to me would just ruin the anticipation. Trying to rationalize it now, it just doesn't make any sense to me. Thanksgiving for dinner just sounds like crazy talk.
