Tag! You're it!

Look what appeared on our front steps last week! Lucy says she doesn't know anything about it, and neither do I. None of the other houses on the street have been tagged. A blue triangle! Pink, I could understand. (David has these very hip-looking eyeglass frames...)

Does it have something to do with aliens? This, from a Welsh newspaper: "In May a 100ft high ...blue triangle was seen hovering over Pont Robert, in Powys. This was joined by a second object covered in ‘pink pulsating lights’."

In fact, the aliens are more than welcome to camp out in our backyard shed. (Watch out for the raccoon!) Or possibly the red-carpeted storage room in the cellar, if temperatures dip below 40. But how do they know that??
