Feb 22 2019 (Sorry for the low quality pics) So you know how Shawn some times does this (look at pics). Well when he (and a lot of other ppl) were babies, their mom would stroke their neck/ back of the neck and head. So Shawn (and a lot of other ppl) subconsciously do this to feel comforted like when they were babies. I learned this in my phycology/body language course, and I thought of Shawn when learning it.
