Yes, the water falls from the sky in big drops. It soaks through the patio stones. The bushes droop under its weight, and the frogs have a new-found confidence because a wet back yard is a frog's favorite world. It is not Jam's world.
Jam prefers to stay inside when it rains. He will reluctantly go out to sit on the porch, but he will not venture beyond on his own, not without a leash, and then with a leash he will only walk along sadly and sigh. He will not pee or poop, not in the backyard when it is raining.
Then at bedtime he is given one more chance. Cheryl and I take turns with an umbrella, giving him all the various encouragements, lies, threats, reassurances, feigned indifference, etc. that we can imagine, because we know that he really needs to go and that the next opportunity will be early the next morning, or rather when he wakes us in the middle of the night, or worse.
And then we remember that our front yard is in a completely different universe for Jam. In the front yard, which is just as rainy and wet, he has no problem at all. Jam is keen to walk along and sniff at every soaking thing, as long as it's not in the back yard.
Surely we have done something wrong...
