ok forgive me for being old but they're saying "larp larp larp" like they're saying she's "Live Action Role Playing" being a "gamer" cause she took a photo of her old DS? am I right on that one?
Misery loves company.
Whenever I see stuff like this online that's the first thing I think of. These people are all miserable, depressed, and alone. The most basic and simplistic forms of joy from others sends them into a "woe is me" rage. They then MUST ensure said person or whomever defends said person be brought down into the same misery hole they dug for themselves.
And you can't just say "oh just ignore them" I'm sorry but no, you can't. I'm sure OP has tried taking that route several times but again these peoples entire lot in life is to ensure you become as miserable as they do. so you can't ignore them.
So what do you do? you keep living your life. Enjoy whatever the ever living fuck you want to enjoy, post about it online, let the miserable cunts try to knock you down, post more. post A LOT more. infuriate them, let them attack you. respond to their posts with a simple "k." or "cool story, bro" or "thank you for the feedback!" kell em with kindness or just an out right virtual pat on the head. "great post champ!" all that. Show them that you're happier then they are and will ever be.
