Sometimes kids forget that not everything is their own personal toy. I've had to give similar reminders to my kids about our dog.
Here's the story behind this thoughtful quote:
"We had an incident at the bowling alley this weekend...My son (5) decided he would try spinning my daughter (2) on her stool. Well, physics showed up, and yada, yada....my daughter ended up on the floor chin first. She had a couple of cuts on her chin and a sore jaw. - Cut to the bus stop this morning....had to remind my son to "be careful, and remember, your sister is not a toy!"
But really, how tempting is a stool to a five year old...
