14 as well. I used to play in a marching band as a kid and we traveled abroad for a couple concerts over a long weekend: picture an unsupervized child surrounded by enabling adults in Southern Germany with access to free beer for one night.
I drank almost 3 liters of beer (yeah German beer is better than any other, sorry), got escorted to my hotel room by our town mayor, where I proceeded to expel my soul via esophagus and… March and play on the morning of the next day.
I was right in front of the bass drum.
20 years later I can steel feel every hit like a clear pain deep in my skull bones.

Welcome to the team.
I hope you brought your bouncing shoes because as soon as you’ll get comfortable, you’ll start hopping a lot
