What the hell is this supposed to mean?
So because we're adults, we're supposed to kick our fandom down a notch? We're not supposed be excited to meet a player we enjoy watching play for our team? We're not supposed to want a memento from when we got to meet our team in person?
Well screw that. I'm 31 years old and I definitely would love an autograph from Colston. That dude has been an upstanding teammate and a huge pleasure to watch on Sundays.
If being a fan of a player makes me childish, well then I guess I'm not interested in being a "grown up."
