Surprises are fun. This could be a surprise run well-done, or perhaps a gift. A few days an "anonymous" person left me a gift on my desk. It was so kind and thoughtful. Although I knew who left it, even though they did not sign their name, my mind instantly went to the back of an old Starbucks cup.
The cup said something to the effect that a person paid for the drink in the car behind them in the Starbucks line, and then that car paid for the car after them and so on.
I love to give gifts, so I got a gift for another teacher which I plan to leave anonymously tomorrow.
Hopefully it will make her day as much as my gift brightened mine :)
