Sleeping Giant

This morning, while I was gone on a run, Spencer got out of bed and went to a friend's house for some early morning yoga. He and this friend have been intensely lifting weights and they decided to add yoga to the routine.
He came home and showered, screeching out the door to get to school on time.
He lifted weights after school and just got home.
"How'd the yoga thing go this morning?" I asked. Spencer isn't exactly a morning person.
He explained how they do "downward dog" and "plank." They do balance poses like "tree." "I fell asleep in 7th period study hall," he said.
"Really?"
"Yeah. I woke up 7 minutes after school got out."
I can picture him with his head on the formica desk, drool dripping from the edge of his mouth.
"Your friends and the teacher left you there asleep?" Earl asked.
"Yeah. They said they tried to wake me up. Then they just left."
As I was writing this, I realized that Tucker shares a study hall with Spencer. I called down the stairs to him.
"Hey, Tuck. Did you leave Spencer asleep in study hall?" I asked.
"Well, Joe tried to wake him up," Tucker said.
"So you just left? What if he'd had a heart attack or something? He could have been unconscious," I protested.
"Mom, it was obvious he was asleep with his face in his book," Tucker explained.
Now my vision changed from him lying with his head turned sideways on the desk, to him face down in his Calculus book. I feel pretty certain that it was his Calc book because that's what he has homework in tonight.
I'm not sure what the teacher's reaction was. Did she try to wake him up or did she give a shrug and close the door behind her? He did give her a hard time when she told them to sit in assigned seats. She might have given a little smile as she walked out the door, leaving a slumbering, and no longer protesting, Spencer asleep.
At least they didn't lock the door.
