Sketchbook app challenge- personal masks

A lot of times we or I find oneself acting how society or our peers expect us to act, in highschool for me it was to not stand out get good grades, laugh with friends, smile always, don't talk about anime, don't talk about video games, don't doodle OC's...Why I bothered to appear normal in front of people I'll only see what every 15 yr reunion? I'm not sure it just seemed important then.
