...Yuri. That's Yuri.

['Sharing with a friend' is definitely a good summary of that memory. Though he didn't consider Yuri to be a friend until years after that moment.]

She called me 'yukiotoko' because I yelled at her. It was her way of saying I had a 'cold heart.' The nickname stuck around for a while, up until we were adults.

I can't believe I still remember all of that so clearly. It happened decades ago.
