I just went to get my lunch out of the fridge and found a second, identical container next to it. It’s not like we’re talking about a peanut butter and jelly sandwich here; it’s some pretty specific leftovers.
So either I brought it in earlier in the week and forgot to eat it, someone else has the exact same pomegranate seed/cauliflower/celery salad, or my lunch is now cloning itself.
Clearly, the 3rd option seems the most likely.
