Yesterday I gave an update to my econ (senior) students - kind of the schedule for the week, because it's different than usual. (Usually it's vocab Monday, book game Wednesday, test day Friday and other various things in between)
After telling them, one of my students said "Whoa, you DO have a heart!!"
It made me smile.
And in that same class, I goofed up on something... and they caught it (not much gets past them). There must've been something in the air, because someone said "Way to go, Miss H!" and they started clapping.
Again, they made me smile.
