When I think of that question I think back to a couple of incidents at the Championships a couple of years.
The first was told to me by a fellow mentor on a local team who was "propositioned" by a student in a way that I'm not sure what kind of girl he was trying to attract. The profanity filters won't let me write it out as is but let's just say she was quite offended and told the student "One. You don't talk to me that way and two I am an adult mentor!" Did he apologize? No. His only response was "For real?"
And second incident was a student approached me on an elevator and asked me a "hypothetical" question about buying porn on a school trip. I told him that school trip probably wouldn't happen again. He thanked me and scurried off, hopefully to correct his previous error.
And basically all I need to do is recall
this classic thread to remember that they are still kids in need of being chaperoned on trips no matter how well they carry themselves.
