We are having heavy rains today. I mean really heavy. So I just took my dog outside in the rain because she just couldn't wait anymore...this rain has been falling for hours and hours. Coming back in I saw a familiar site; hundreds of earthworms driven onto the sidewalk by all the water. That is my question...why do they do that? Don't they "understand" on some wormy level that they need to be in the dirt, so once they get out and see that they aren't in dirt anymore, why don't they just go back and go in a little deeper? When I can, I do pick up living ones from the sidewalk and put them back on the grass. They always seem to wriggle happily when I do that, so why do they put themselves in that position?
I'm just asking.
