Hey I need advice:There is a track meet I have to go to today and I really don't want to go. This is because my teacher is going to be there and I really don't want her to see me because I do online and my parents will make me speak up too loud to her and I don't want her to see my twin. Anyways how would you raise your core body temperature in a few hours for real? Please don't report. This is very important to me. Thank you guys I really appreciate!!!!
