I just happened to glance out of an upstairs window first thing this morning and spotted this woolly intruder. I grabbed my camera and as I opened the front door, the sheep looked up with a guilty expression on its face. It's clearly saying, "Uh, oh! We've been rumbled." :)
There were actually 4 of them, all happily munching on our front grass. I would have been happy to let them stay and mow my grass for me, but I knew the neighbour wouldn't want sheep eating their plants and anyway it would be best to send them home before the road got busy.
A quick bit of sheep herding later, they were safely back where they belonged, behind a gate with a sign saying, "Please keep this gate closed or the sheep will get out onto the road and into people's gardens." Either someone had been careless (though the gate was shut when I got to it with the sheep) or the storms have created another way out and the sheep have found it.
