Whyy did he try to cover me more up in the blanket?

i was hanging out with this guy. we were cuddling and watching t. v. i had a blanket on me and he put his hand on the other side of me to try to cover me up more with the blanket. funny thing is, i was wearing a fur vest and he thought that was the blanket he was pulling lol. my question is why did he do that in the first placee?
