As Janis said in Mean Girls, Oh, "I love seeing teachers outside of school. It's like seeing a dog walk on its hind legs."
Teachers shared how they spend their time after work (aka school), and it's not just spending hours and hours on Reddit. Some activities would definitely get them detention.
I've hooked-up with some of their moms. I'm teaching in a small town where I also grew up. It happens. Still... I don't talk about it.
Native English Teacher in a non-English speaking country here, teaching elementary age. I begin each class by saying, "Good morning, class," to which they respond, "Good morning, teacher." Sometimes, if I feel the energy level is low/response is mediocre, I will say louder, "Good morning, class!" This will usually elicit a "GOOD MORNING, TEACHERRRR!!!!"
What my students don't know is that sometimes I'll aim for them to repeat loudly so as to mask a wicked fart I need to let out.
