When I was looking at various blogs, I found a lovely story about a random act of kindness on Rummey Bears. Consider reading it.
It's also a nice reminder about those lost opportunities. Those times when we our first impulse is to help, but there is also an awkwardness or an unease so we step back and don't end up following that initial response.
Perhaps we need to do more about listening to our inner voice?
Well, I don't know about other people...as for me, I'm going to listen to it more often.
