How to shoot a gun at camp?

Arrival

Once I arrived at millstone camp, my stomach hurt. "Ok, have fun. You wanted to do this camp." My dad said as I started walking to my cabin. "Yeah, because I was forced to pick a camp. And my stupid little monster sister doesn't have to!" I thought as I met the counselors.
When we opened the door, the cabin had bunk beds and I picked a bottom bunk. I unpacke slime everyone else. Afterwards, we went and played "ga ga ball". It's a game where your in this closed in area and you slap a ball around. If you get touched by the ball, your out.
Then, we shot rifles as our first gun lesson. After this, lights out and time for bed.
