Never Look a Gift Nectarine in the Mouth

Recently eaten: grilled cheese
Recent annoyance: one sticky contact lens

This morning I arrived at my desk to find a nectarine on it. not just any nectarine, but a fragrant, perfectly ripe one. At first, I figured an absent-minded coworker had come in to my office and left his/her fruit on my desk. Then I noticed a nectarine on Daniel's desk too. Where did these mysterious fruits come from?

No matter, I ate it, so if it was poisoned, woe is me.
