Batteries

On Tuesday night, I found out that my keypad is battery-operated and that those batteries eventually expire.

Yep, I unknowingly locked myself out of my apartment.
Since I had gone for a run, I left my keys and cell phone in my apartment (as usual).

To make a long story short, a kind pregnant woman in the beauty shop next to the maintenance office helped me make a phone call. We were able to communicate with my very limited Korean and her limited English.

I waited.
Maintenance man came.
Exclamations in Korean.
More waiting.
Two locksmiths came.
More unknown Korean exclamations - a little more gentle this time, though.
Door opened.
They collected 20,000 won.
I learned that the battery was dead.

I didn't even know my door was run by batteries - let alone that they would need to be replaced...
