what will a high-school do if they find a child with a small empty bottle of liquor?!
likely depends on the schools policy, and the location
could be anything from just a slap on the wrist, to expulsion
in some european countries, it wouldn't be an issue, since many places teens are legally able to drink alcohol.
When you say child do you mean a little kid like 5 years old or a teenager? If it's a small child they will probably contact child services if it's a student they will be suspended or expelled
If the bottle is full the gym teacher would hand him a twenty and have him forget all....
