Finding ten bucks in a laundromat happens, like, ALL the time.
Someone stops at an ATM on the way, comes in with a 20, takes it to the counter and breaks it into a $10 and ten dollars worth of quarters to do their laundry. They stick the other $10 in their pocket, and somewhere along the way it falls out.
Or someone just left some cash in their pocket and didn’t double-check the dryer before leaving.
So it’s absolutely a coincidence, and not even a terribly surprising one.
Now, if someone came home and said, “Guess what I found in the laundromat today?” and the guess was “B B King’s Gibson ES-355 guitar, Lucille?” and the dude was like “YES HOW DID YOU GUESS?!?” and then whipped it out and started playing “Rock Me, Baby”...
THEN you can talk to me about ESP.
