This is not a note
Growing up, our moms sent us to school with a boxed lunch and an endearing note wishing us a lovely day. This is a sweet gesture when we’re young, but all children get to a point where they stop finding these gestures as sweet, and start finding them as childish and redundant. When this kid asked his mother to stop with the notes, she didn’t take it very well.
It might be hard for parents to accept that their kids are growing up and they might not need them as they used to. This mother respected her son’s request, but she made sure he knows how she felt about it, as she attached to his lunch a note saying this wasn’t a note, but a poor choice of napkin.
