A jacket!! :)) Well, I am sure you were chilly if you put it on! I must say that I sleep with the windows open all year long, except when it is too hot. Even at 0C or less, I love it as I like to be warm but in a cool room.
Generally, I am not ever cold, except on rainy days.
Memorial Day was this weekend and it was very busy, but, a nice military remembrance day.
I don't like cold weather at all😅! It sounds like you are like my youngest daughter's husband... He's also never cold...hahaha.
I'm glad you enjoyed Memorial Day, even though it was busy!
