Well for starters, why did you have to leave it behind and why was it sold? Im a grown ass man and ive got pony shit in a glass case alongside my weeb shit.
Part of it was to make room in my car for things when I move out of state. Another part is letting go of things that I kept a hold of for maturation reasons. Can't really maintain or collect comics when you're driving a ratty car and living in a shithole. Maybe in the future I may collect stuff again, maybe I can set something up, but in the meantime, I'm keeping only the shirt and book, cherishing the past and fandom I'd been a part of but also setting it aside while I start my adult life for real.
Also I'm unemployed and in debt so the $400 was definitely helpful for the moving effort.
You can still have a few comics I think. You can probably still find them to buy
The most childish thing you can possibly do is have an irrational fear of childish things, fag.
