I can't read thai!

A few weeks ago I open my mailbox (for the first time), and see a piece of paper written entirely in Thai, with a number, 187, written on it several times. I look at it for a while, realize I cannot read thai, then stick it on my counter, where it remains for 2 more weeks. After 2 weeks, I clean my apartment and throw away the piece of paper. Today, everything in my apartment suddenly turns off. After an hour of sitting in a blazing hot apartment, with no internet, I finally realize that this wasn't a mistake (occasionally the power will shut off), and that piece of paper I threw away was my electricity bill. Oops. Fun times in a foreign country.
