The Pandas and the Neighbor's Bamboo

I am hearing munching and chewing sounds coming from the yard, and one of the pandas just trotted in looking to see if we might have a wok handy. They raided the poor people down the street's bamboo patch, I just know it! Can I be held in any way, shape or form responsible for this? I hope the didn't make the mistake of leaving a leafy trail back to our house. About the only good thing I can see is that it seems they waited for the cover of darkness to visit the bamboo. Pandas are mostly black, so hopefully they weren't spotted.
