Anecdote one: a few years ago I took a road trip with my friends Aaron & Wes. The purpose of the road trip, ostensibly, was to cheer up Aaron, who was feeling exceptionally lonely as he had no girlfriend, and worst of all, Kirie, his beloved dog of 14 years had passed away a month before.
In the middle of the Nevada desert, when Aaron sighed & said "you know what I'll miss most about Kyrie?" Wes chimed in with "the feel of his furry little nuts resting on your chin?"
I think we all learned a lot about ourselves on that trip.
Anecdote two: When I was in the early stages of my relationship with the future Missus Jonson to be, she was waxing poetic about an old boyfriend, specifically contrasting my constant state of worry & negativity with his eternal optimism. She mentioned that the source of his sunny disposition had been a bout of testicular cancer that had claimed one of his nuts, and nearly his life, in his late teens. After that scare, she said, life's little worries never got to him. My immediate response was "so he's more of a 'my sac's not half empty, it's half full!' kinda guy, then?" She was not spectacularly amused, but I swear in my thirty some odd years on this planet I've never been nearly that clever before nor since.
