I don't know why, * maybe it's an autistic thing but I find wearing a hoodie to be just so damn comforting. It's like a blanket that you wear like clothes! Too cold in your house? Zip up your hoodie and relax in your computer chair! Too chilly outside? Zip up your hoodie and go for a nice relaxing walk! You don't even have to wear the hood—it's just there so you can call it a "hoodie" instead of a "sweatshirt".
Not a huge fan of hoodies. It doesn't often get cold enough for me to want to put the hood up, and when the hood is down it's just a useless encumbrance.
Be not afraid...
