guerilla gardening gone wrong

Earlier this spring I planted a packet of morning glory seeds with the goal of planting them at various places around the yard. There's also a no-parking sign by the street that is kind of dull to look at, so I was thinking how neat it would look to have a morning glory tendril winding around the signpost and bursting into bloom.

So yesterday evening I'm planting it, when my neighbor comes down the street, sees me working by the post, and asks if someone knocked the sign over, as has happened before.

I explained what I was doing, and he said, "Um, Dave, you know this is my yard, right?"

I was mortified. It's about seven feet past the property line, so there's really no way not to think the sign isn't on his property. I don't know what I was thinking. It just flat-out didn't occur to me that I was digging a hole or planting a flower in someone else's yard.

I apologized profusely, and he was really cool about it. He even suggested other neighbors' yards where I could plant morning glories, suggested some work I could do in his back yard, and joked that he might come over to my yard and remove a few bushes that he doesn't like.

If there is an election held this year for Stupidest Neighbor on the Block, I think I would win hands down.
