The One Time My Sister Lost Her Bear, And I Found It, And Revealed The Finding At Great Personal Risk

My sister as a little child had this kind of ugly teddy bear she called "white bear" (we were creative. my item was called "yellow blanket". laaaame). I went to the elementary school, I was in the 3rd or 4th grade, so she would have been 3 or 4. She went to a preschool across the street, and both schools shared the playground. So one day she came home from preschool with no bear. No bear!! I think she kept my mother up all night. This was before ebay and no replacement bear could be found. It was a disaster. She didn't sleep for days.
Then one day I (through no fault of my own, obviously) ended up sitting writing lines or something in the principal's office. On the desk where I was working was a bear just like the missing one.
So there I was with a third grade dilemma. Do I go home and tell my mother that my principal has a bear in her office, and possibly knows where to buy them, thus revealing that I had been sent to the office?? or do I keep my mouth shut??
I told my mom. She went straight into the principal's office and begged to know where the bear had come from. Turned out, the bear had been found on the playground--it was the same dumb bear.
All I got for being sent to the principal's office was a tight-lipped "hmmmmmmmm" a la Marge Simpson.
The funny thing is my sister remembers it all differently. If you asked her she'd probably say I tore the stupid bear from her hands and hid it myself. All her memories are me as a complete bitch.
