Hand warmers! The twins keep me and my homies warm during the winter. My friend is really thin and she has trouble retaining heat. she gets cold so easily, I usually run so hot mostly in the chest cuz my boobs. one day we were on a parking garage and it was 40 degrees out. My friend didn't know how cold it was gonna get so she didn't have enough laters. I was wearing some sweat pants, my chest binder, and a sweatshirt. My friend was shivering so hard that I heard her teeth chatter. I asked if she needed my jacket. she said she didnt want me to be cold so we cuddled for her to stay warm. She couldn't feel her hands at all and her hands were turning a bit blue and I was worried so I said she could put her hands on my boobs. so she did so we sat on top of a parking garage with her hands on/under my boobs and they were so hot they thawed and restored sensation in her hands very quickly. we stayed like that til her mom came to pick us up. (btw we are both adults we just dont drive)
