This is a departure from the “Color-Coding” theme, but a good tip. I set all of my garbage cans/recycling bins on top of chairs. As we’ve all noticed many high school kids are apparently just a little too tall to be able to successfully navigate trash INSIDE the trash can. They are also so tall that they can’t see their garbage all the way down there on the floor. Raising the trash receptacles to hand level eliminates 99% of that nonsense.
And yes, it is definitely time to take out the recycling!
