Pet Burial?

Another Memorial day weekend has gone by. Here it is, June 1st. We had a fairly uneventful weekend, visiting with each set of parents for a bit. The only excitement was provided by our charming neighbors upstairs. There was some strangeness going on in the backyard, which I'm far too nosy to have ignored. They had scraped back the mulch and were digging a hole about three feet deep. There was a suspicious black plastic garbage bag next to the hole. After the hole was filled in, and the extra dirt taken out was tossed over the fence, a lovely "rock garden" was displayed over the top, and a poem was read while everyone held hands in a circle. My first thought was a pet burial of some sort. When I asked our landlord about it, they had no idea what I was talking about, but they were pretty sure no one asked them if they could dig up the yard. Anyway, Upstairs Girl told them that it was just a rock garden, that they had dug a hole and filled it with rocks to "support" their creation, and that the whole reading in a circle thing had been them "blessing" the rocks. Apparently the landlord believes this crap. So, what was in the garbage bag? And did I mention the black cat with them on a leash?

Hopefully we will get some info on the possible job for M soon. Sure would like to move out of here...
