I knew a kid in elementary school who moved from Trinidad to New Jersey, and that first chilly day of fall she came in still dressed for summer, teeth chattering. We were all like, "why are you in shorts and a t-shirt??" She said that they hadn't gone cold weather clothes shopping yet because they didn't realize cold weather hit that early, lol. Poor girl was freezing her butt off until her family got to the store later that week!
