Why would a snail want to climb up the side of our house? There's a snail trail from the path up to the roof (you can't see it on the photo but believe me it's there, although I am a bit disturbed by the fact that I have tried to take a pic of a snail trail!). Do you think he's just lost? Where is he now and do think he fell down or slid his way down? One of life's mysteries.
