Here's my view on teams and their demeanor:
Some teams collectively are made up of players that have a sober attitude, all business, reserved and stuff like that. Their overall composure is a collective of personalities. Your demeanor just happens to be one that's just the opposite from theirs.
So let me ask you this - why not change your demeanor to match your teammates, instead of all your teammates changing their demeanor to match yours? I think it's a fair question and reasonable - don't you?
On the other hand, if there are undercurrents going on within the structure of your club, then that changes the entire picture here. If so, you're walking a very tight line, like trying to reach for the moon.
Teams in competitive baseball have mandates and issues, dictated by environments, that are impossible to digest at your age. So, with respect to the digesting remark ... be careful not to bite off more than you can chew.. that mouthful can get stuck in your throat ... and virtually impossible to digest.
