I saw a lady and her two kids leaving Wal Mart yesterday afternoon. One of the kids accidentally dropped lots of coins on the ground. The mom and two kids frantically hurried to pick up all the coins..... except for the pennies!
They left a few on the ground. I was already in the doors of the store by then or I would have picked them up myself.
I almost always pick up pennies.
In high school we used to super glue pennies to the lunchroom table. Drove the lunchroom monitor crazy. She'd work really hard to get those pennies free.
