THE MYSTERIOUS PIZZA

It started a month ago. Every Friday, a pizza delivery guy shows up at my door with a pizza I never ordered.
At first, I thought it was a mistake. I told him, I didn’t order this, and he said, It’s paid for. Enjoy.
Next week, same thing. Then again.
I have no idea who’s sending them. There’s no note, no message.
Some of my friends think it’s a secret admirer. Others say it’s probably someone trolling me.
I’m not complaining free pizza is free pizza. But it’s kinda creepy, don’t you think?
Anyone ever had something like this happen?
