God love em! We always say that and mean it. Who else will wipe your kid's nose, and bottom if they have to, teach them to tie their shoes (and actually enjoy doing it), wrangle cafeteria duty with love, teach their hearts out, even if against all odds and standards, and so much more...?
Like throw their bodies over their students' bodies to save their lives in a tornado...while they can't be sure, for sure, where their own kids are and if they are safe.
Teachers are first responders, are heroes, and knew "Leave No Child Behind" long before it was a buzzterm.
Hug a teacher, kiss a teacher, buy a teacher a useful school tool present, or maybe just a lovely beach towel. She (or he) will probably just wrap a wet kid in it or wipe a nose. It's what they do. We should appreciate it more.
