Dad can you get me a wash cloth I love being a father

Our one son hollered to me from the downstairs shower. I was sitting at dining room as he showered, ok no problem. So I go in hand him wash cloth and then as I hand him wash cloth. I reach into shower and back hot water off to cold in stealth mode talking to him. as he says thanks dad. And I walk out and I hear REALLY DAD as the cold water hits him. I hear I was rinsing the shampoo out my hair I just smile. And his brother and I laugh their both thirteen.
