Thanksgiving in my imagination.
I think we're saying something like this:
Mr. K: What's this? I thought we were getting together for a meal.
Suzume: Who needs that when you can just have pie?
(to Kimblee's left) Miss M: ...I wasn't supposed to dress up, was I? Because no one mentioned that beforehand.
Suzume: No, of course not, they [Kimblee in particular] just dress like that all the time.
Happy Thanksgiving to all of you and thank you for being my friends! :)
