Nothing is strange.
To me it seems more strange to block your passion and deny yourself an amusement just for STUPID social "clichés". ;)
I am 48 years old, I use video games, I read Manga, I watch Anime, i drawing, i enjoy!
But I work, I pay taxes, I do all those things that "adults do".

We need to stop thinking that being an adult is KILLING THE CHILD PART OF US.
That's where fantasy, joy, passion, your hobbies, and everything you like live.Killing that part of you, kills the part that brings you joy.

Psychologists today know this.When you're sick, the first thing they recommend is to find passion. to dance, to draw, to play.
To find that side they lost, that side that was their generator of joy.
NEVER BE AFRAID of doing what you are passionate about, just because you have to be HOW OTHERS WANT YOU! ;) have fun!
