It is creepy.

Look at this:

Here is an adult man, who has no reason to be interacting with high school children, that has decided to devote 7 months to figuring out how he can change their behavior to what he considers appropriate. To force a child, or anyone else to respond to you is the perfect illustration of privilege through perception of threat. Same concept that leads men to tell women they do not know and have no reason to interact with to "smile for me." It's awful, just leave people alone.

Don't force interactions with children 1. that aren't yours 2. you do not have any reason to interact with. Something to think about: https://en.wikipedia.org/wiki/Child_grooming
