I blinked... and Dylan isn't class troublemaker anymore

Two short months ago, drop-offs were a nightmare. I had no idea what to try and little hope my little man would be one of the quiet, well-behaved munchkins getting folders and their name card to put in the basket and then calmly walking to the carpet.
Now I grant you, he's far from flawless in his execution. Dropping Dylan off at Headstart today, he was telling me his belly hurt. But as we pulled up, we were stuck behind the ATA bus for his classmates and an employee who works in the same building waiting for access to the parking lot. Someone behind him didn't understand they could go around, so we ended up in a five-car traffic jam on a narrow street. As we are waiting, one of Dylan's classmates begins holding up the already tenuous process of getting the line of kids into the building. He is moved from the middle of the line to the end with the teacher. Still struggling, they try to use logic, pointing to the cars and explaining they need to get into the spot where the gaggle of kids is currently located. Failing with logic, the teacher employs the next logical method - pick him up and away the line goes into school.
I told Dylan one of his classmates was having a rough day, and suddenly the repeated "My belly hurts. My belly REALLY hurts." ceases in the back seat. Suddenly he wants to see who is having a bad day. We park the truck and go into the building, following another classmate and adult. We go into the room and I accidentally almost knock over this classmate, who thirty seconds in has had enough school for the day and is fighting to get back out. The teacher is once again employing logic. Again, fail. This little boy's mom opts to take him home. The other little boy is already on the carpet with the other kids.
Dylan demands I take his jacket off, takes care of his folder and then the hesitation starts. But this morning, distraction works and there is no screaming, minimal disagreement and Harper and I are out the door.
Compared to his classmates, Dylan is the quiet and well-behaved one.
My gratitude for this realization knows no bounds.
