This was unusual the first time it happened; now that it's happened twice, I really want to know what's going on...
I was playing by a fountain in the Public Garden, and an older Asian gentleman dressed in khaki shorts, a white T-shirt, and a cap or visor (I've forgotten which) got into the fountain basin, sloshed around for a while, and left. Same thing happened again a couple days later.
The first time, the basin was mostly full; the second time there wasn't much water in there. The only thing I can figure is that he was looking for coins, but do many people toss coins in those fountains? They just don't quite seem like wishing fountains to me. (Toss the coins in my case! In the case, people!)
Speaking of my case (look, a rare and elusive segue!), a disheveled man came up to me (waaayyy in my personal space) and told me I shouldn't have it open like that because there was "too much money" in it. Since I was playing at the time, I just smiled and nodded. Then he closed my case.
I stopped playing, flung the case back open, snarled "If it's closed, people won't put money in it!", and glared. He wandered away looking at me like I was terribly rude.
There were only about five dollar bills in it anyway.
Someone requested the Pachelbel Canon today (and if you don't know it by name, you do know it. It's played at every wedding anywhere ever). It wasn't really so much of a canon since it was only me, and for as many times as I've played it at weddings, I stumbled badly through a couple transitions, but my audience enjoyed it.
(For those of you familiar with it, yes, I only hit highlights.)
After I finished playing and headed to Starbucks, a nice Thai gentleman followed me there. He'd been sketching me and wanted to know (very nicely!) why I'd stopped playing. I told him I was expecting my ride, talked to him for a bit, he showed me the sketch, which was clearly not quite done.
I would have felt more badly if I hadn't recalled he'd been photographing me quite a bit as well.
