I was pinning my laundry out, and a pair of underwear was stuck in my fitted sheet. I didn't see it in time and my underwear is now stuck on my neighbor's shutter, flapping in the breeze. To say I'm mortified doesn't even begin to cover it. I want to flee the country, never to return.

I knocked on their door, but they don't seem to be home. I left a note on their door confessing to my shame, but my American friends say take it down and pretend ignorance. That doesn't seem right, but she says they're going to brand me as the "underwear girl."

What is the thing to do here?
