Lies of Convenience

The other day a haggard-looking gentleman asked me for some change as he walked by.
Living in Toronto now for about 6 weeks, I have noticed that this happens much more regularly than when I lived in Ottawa. I've walked by people all over the place who look as though they need my money more than I do, and yet, not once have I 'spared some change'.
Actually, that's not entirely true - I have paid out a few times for street musicians.
There's a guy in one of the Subway stations that plays an amazing old-school blues guitar, and his sign says "support real blues", or something to that effect, and he's actually really providing a decent service to the commuters, so sometimes when I see him, I throw him some change.
There's also a group of shirtless guys that play some acoustic guitars right across from my work.
They look like they're genuinely having a good time, and rarely stop strumming to tell a tale of woe and ask for change.

Anyway, I digress.
back to the haggard-looking gentleman.
When he approached me, he held out his hand, and I shook it.
He offered me his name, and started to explain his situation, but I cut him off and said that I don't have any change, which wasn't true, I had a pocket full of change actually.
I didn't mean to lie, but the truth was that I genuinely needed the change that I had.
I could've said, "I don't have any change 'to spare'", but no, I said "I don't have any change".
He said that it was ok, and wished me a good evening, then as I started to walk away, he asked me what day it was.
I told him it was Wednesday, and continued walking.
When I got home, I realized it was actually Thursday..
The Moral:

"A man lost in lies, rarely remembers the truth"
