I only get upset if the younger player is the stereotypical "I'm better than you and I banged your mum" squeaker. If you act mature/your age I could care less what your voice sounds like. If you need help I'll help you but if you're being annoying on purpose you're gonna get kicked. If people are kicking for no reason other than a [i]slightly[/i] higher pitched voice, that's not cool. [spoiler]I said "slightly" because at 13 your voice (or at least mine) was staring to deepen.[/spoiler]
