Keels and I went grocery shopping awhile ago. While we looked at different brands of mustard, I randomly whistled, just one short note, increasing in pitch. Then I glanced to my right and saw an older woman (in her 40s, maybe?) walking down the aisle toward us, and I made eye contact and smiled, and she said "hi" and smiled very shyly and sweetly...
And I realised she thought I'd whistled at her.
And as we walked away Keels tried not to laugh, and she said, "She was hitting on you!"
And I said, "Why did I WHISTLE?"
And she said, "She tried to steal my girlfriend, dammit!"
