Why do people post this unironically

Hahaha this was me in school. I was so popular because of my jokes and comedy. If I didn't go to school one day, the whole class would say it was a boring day. Apart from that, I didn't do anything else with my friends, I didn't let them come into my private space. At home, the life was a little different. I had a stressful relaionship with my parents, that is to say.

Well, I didn't use internet back then so I had no idea why I was sad and cried at home, but super comedian at school. Now I am 22 and I have realized that my true personality is an introvert. I practise more and more silence and am not as energetic and comic as I used to be. But when I look at other people cracking jokes and enjoying the shit out of life, I feel nostalgic and sometimes miss the old life. No one currently in my life that I Used to be a class clown... does that matter? should i let them know? or bury it as a past? and embrace my introvert and thoughtful new personality?
