Not really! I can sleep anywhere...but I prefer a bed, and my bed is the best option, because I'm used to it.
I'm very picky about my blankets...my parents don't care if I make my bed, but I end up making mine almost every day anyways, just because if they aren't almost perfect I'll hop in and just get out and make it anyways! They have to be almost even on all sides, and all of them have to cover my feet. I like them to cover my shoulders, but if I have an arm out of the covers it's okay for them to not. I also always sleep with my heavy winter blanket, I'm used to the weight of it on me and sleeping without it irks me far too much.
Sometimes I'll wake up sweating in the middle of the night, take it off just enough for me to cool down, and then put it back on again. Lol.
I can't be cold. At all.
Your math completely baffles me to be honest. Most people in my grade were in Geometry Honors or at least Geometry...nope...I was in Algebra! And my grades stayed in the 80s all year...I'm the first to admit that I am completely math dumb! Thank God for calculators!
