Ah, and now we get to the heart of the matter.
How is that "the heart of the matter"? I can and do see my wife in underwear every day, how freaking sad are you if you think that Halloween is awesome because you finally get to see your wife in skimpy clothing?
I think I've been fairly clear about what the heart of the matter is. Growing up in a country where Halloween isn't really a thing, seeing the level to which people go over here and the behaviours that they attach to it is bizarre. That is the heart of the matter.
Equally, Thanksgiving means absolutely nothing to me. It's not a thing in the UK. At least they don't expect me to dress up as a Disney princess in order to eat turkey though.
