Humidity and cold room temperatures. Happens in my house every winter.
It is, what thunder and lightening is.It makes your jumper crackle, when you pull it over your head.It makes balloons stick to the ceiling, after you have charged them up by rubbing on fabric or hair.It makes your clothes stick together, when you get them out of the tumble dryer.It gives you a shock, when you insert the key to a hotel room door, after walking on synthetic carpets.
The same way you got in.... the door. The same way you got in, the elevator. Remember to take the stick with you...
It shouldn't hurt anything. I like to if the door to the room needs to be closed. It makes so your room doesn't go so stale.
