Because Strangers Don’t Help Strangers
This texter wanted a total stranger to take Val to school in the morning. Yeah, that’s an excellent idea! Why don’t I just punch in a random set of seven numbers on my phone and ask the person on the other end to take our child to school for us? That doesn’t sound like a recipe for disaster at all!
The OP was even kind enough to inform this passive-aggressive parent that they got the wrong number, but that wasn’t good enough for them. So, they dropped everything they were doing to take Val to school before trying to guilt the OP for not lending a helping hand.
