Parchment paper was sitting absolutely flat and motionless on the counter and there was no wind in the kitchen. I am puzzled...

Moisture.  I had the same experience 2 days ago putting parchment paper on my counter to deposit the pizza that was baking. ?  I buy square sheets and had just cleaned my counter.  Every sheet I deposited curled up slowly, exactly like that!
