I was somewhat concerned when we took our son to school this fall for his freshman year. He's an outgoing kid but sometimes doesn't tell us all that's on his mind.
When my wife and I returned to our hotel room after the first afternoon's orientation program he called us and said he was in the coaches office and had met up with a few of the upperclassman who asked him to go to the cages with them. He was truly excited, and hasn't looked back since.
One of the things that helped in his transition was a group of teammates and friends from the first day.
