You will also have more trash left along the sidewalk and in the street. In this area it is not too bad. The neighborhood has lots of friendly people that I talk to on a regular basis, and is close to so much.
A thought is to go and talk to your would -be neighbors, see what they have to say, see if you can get along and be happy around them.
But if you're the type that loves the hustle and bustle of a neighborhood or central activity area, living across from a high school would most likely be fine.
Bottom line, try to predict how you feel about a place a few years into the future.
