I see an SJ also advocating celebrating Thanksgiving by eating turkey, but for a different reason.
They celebrate it because that's the known pattern. That's the right thing to do. They won't go all lyric on the "meaning" of the holiday. They want Uncle X to come not because they want to see Uncle X again, but because it is a family holiday.
My ESTJ husband confirmed this
Differences between ESTJ and ENTJ? His first reaction: ESTJs are more conservative.
