"Pishing" Today

Today is a good day. Our daughter's family is coming for a visit. Our grandson Dawson (4) called us Thursday evening. He wanted to call Mamo, but as my grandchildren are prone to do, as soon as I answered the phone, he said, "Mamo? I wanna talk to Grandad." He wanted to tell Grandad that when he comes to see us, he wants to go with Grandad and Sassi in the Mule down to the creek to go "pishing." So, guess what Grandad will be doing this afternoon?
