Besides, everyone will grow up and older as years pass by, then a fresh batch of newbies will come along... and the cycle will repeat itself. So, rather than terrorizing the new RPers just because we had a bitter past experience of sorts, we should stop spreading bad habits to the next generation, and always remember that we were also in the same boat as them when we just started RPing years ago.

(There are assholes out there whether we like it or not, but what we can do is just don't be one of them, and don't entertain their idiocy.)
