It was raining quite a bit this week and the central courtyard where Duncan usually plays at NVIDIA had accumulated 4-6" of water. I was on my afternoon walk with Duncan (mandatory rain or shine) and as he lunged to play in the courtyard, I figured heck, we were both soaked anyway, let's see what Duncan does with the pool of water.
At first he tip-toed in and sniffed it suspiciously. Then he took a few steps and the water splashed up onto him. He stared intently at it, challenging it. After a pause, he swatted at it and it splashed him in the nose. Then I saw his face light up and he started splashing with his front paw. He ran a few steps in each direction kicking up water all around. This escalated quickly into jumping and finally a full gallop back and forth and back and forth at top speed tearing around with paws lifted high splashing and biting the water leaving a rooster tail of water behind him.
Part of me that was screaming for me to stop this wet, muddy, dirty, inappropriate-for-work madness but instead I just let him be. His look of sheer bubbling joy as he playfully splashed around was more than worth the strange looks I was getting from coworkers and the crazy cleanup that followed. I've honestly never seen Duncan have so much fun in his whole life and it warmed my heart to know that he was happy.
