When my kids were in elementary school, the custodians at their school were wonderful.
Not only did they deal with the daily grind of keeping up the school, but were there after hours cleaning up and helping with PTA functions, Book Fairs, Secret Santa Shops, and more times than not, hauling our stuff in and out from the parking lot.
There was one student who had seizures at our school, all the time, and one of the custodians would always pick him up and carry him to the office and was genuinely concerned about this kid.
