are you crying?

Husband had to spend a whole day teaching yesterday.
His topic was entrepreneurship.

"What grade are you teaching?"

"First."

My eyes watered.

"…wh-where are you teaching?"

"West Valley."

I wept.

"Are you crying?"

"It's just… they are 6 and 7 year olds. It's hard to teach kids that age something that they aren't interested in. Especially for a whole day. And you're teaching business…"

"Entrepreneurship."

I cried harder.
He didn't understand why I was crying, when he was the one going to be stuck in a room with them all day.

To be honest, I don't really understand it either. It was an emotional time.
