DD plays a video game (a lot) and is almost 19. She wants her first tattoo and has had a design done which is literally a character from the game. As she's so young, it might seem cool now, but I really think it's the type you're going to regret, she won't play this game forever. She plans on using the birthday money from us (she is a uni student so doesn't have another way to fund it really) so I'm slightly reluctant to now give money on her birthday. AIBU to have these feelings and persuade her or?
