Thanksgiving

So I always wonder why Thanksgiving is a day of gratitude and we celebrate our gratitude by killing a whole bunch of turkeys. It doesn’t seem to need to be a way of expressing gratitude to gorge ourselves and overeat and express gluttony. It would appear to me, in fact, that the opposite of gratitude, that that’s abuse of God’s great gift to us, which is health and which is life, and killing a bunch of turkeys and overeating and being unconscious are they an expression of gratitude, seems very strange to me.
