When DS was 6, I came home to this message:
"This is the school nurse at _____ school where DS goes, Poison control says he'll be fine." WHAT!!!! Turns out it was just a little hand sanitizer a classmate smeared on an apple slice he gave DS. I made kid's mother cry, calling him psychotic. He was and she knew it and cried over that. More things happened after that.

Then once DD's High School called to ask me why I hadn't called in her absence? WHAT!!!! Last time I saw her she was walking to wait for the school bus. Later they called to apologize, she was right in class, mistake made. Sorry.

Once the heart starts pounding, it's hard to calm it again. Whew.
