Maturity

For the uninitated, we're talking about a video game from the notoriously violent Grand Theft Auto series.

“Mom wanted me to call you and find out if it was okay for me to play Vice City. I think it's okay, because I'm seventeen and everything, but mom said she wasn't sure and wanted me to talk to you about it since you've played it.”

Wil Wheaton has a good answer to this question.
