How to make a mom cry, before 8:00 a.m. is quite easy, actually!
1) You have to be a boy.
2) Make sure to get dropped off at "the circle" in front of school about the same time as Angela.
3) While Angela is walking into the building, and while her mom is waiting to make sure she makes it into the building without dropping anything, holler from the opposite side of the circle (50 + feet away.) "Hi Angela!" and wave enthusiastically with a big grin on your face. Then add, "Hey, wait up!" as you hurry to catch up to her.
4) If Angela grins from ear to ear, covers her mouth, and turns to check if her mom noticed this exchange, there will be extra tears from said mom.
