Pajama Problem

I strongly dislike wearing uncomfortable clothing. I was thinking about this when I thought, "I wish  could wear pajamas to school." Then I realized, what's stopping me? Wearing pajamas in public is frowned upon, and I don't know why. I have often looked at pupils wearing pajamas in public with disdain in the past. The reason why I "can't" wear pajamas to school is because it's not socially acceptable. Why should I care what others think? Am I wearing tight, irritating jeans for me, or for others? Still, I am wary of the idea of wearing pajamas to school.
