The Commonplace of Irony in Life

So, yesterday I decided to venture out into the world for the simple pleasantries of ice cream and decent weather.
Needless to say, I decided to sit outside. I found it more than interesting when life’s odd and rather funny plan unfurled before my very eyes.
I spotted an old childhood friend of mine. Over the years, we had lost contact and our bond faded into the oblivion of familiar faces. I didn’t say hello, because I knew that she’d most likely forgotten me, but I found it very entertaining, either way.
Has something like this ever happened to you? If so, what was the end result?
