Opening the door without using your hands.
I know most people don't have to worry about this unless you're in marching band or if you're me. At my school you don't really need a backpack because you are inly required to have one 3in 3 ring binder an if you're smart, you'll get one that zips up and has a handle. So carrying that binder plus my trumpet case and a lunch box keeps me from opening the door with my hands (plus I REALLY don't like putting my stuff on the ground). Luckily after practice I learned to open the door with my hip so all is well! 👍
