I’m sorry, but what? I’m a dad to a teen and a new teacher as well, so I have experience in this area.
Everyone is unhinged. Get a grip.
You really don’t understand the profession of teaching if that’s your takeaway of what I said. We all get frustrated with students, but to plainly say “shoot” them, while in a literal school and over social media because a student closed your laptop?
A student teacher shouldn’t be this frustrated at this point in their career or they should consider a different career. Kids do this stuff all the time, especially to each other. Open the laptop, boot up, recover the documents/projects. It’s really not a big deal that warrants a comment about shooting a kid, even as a joke.
If you really feel that is acceptable, then thank you for not teaching kids.
