sorry about your lunch

In Spanish one day, somebody from another class had left their lunch in the room. When the teacher walked in, she asked whose lunch it was. Since none of us knew, she asked who wanted his (or her's) brownie. She proceeded to give away the brownie, a nature valley bar, two ham and cheese sandwiches, and a bag of grapes to my classmates. Nobody complained about being hungry that class. Thank you, mystery person, for your lunch.
