~ From www.dictionary.com
By sheer serendipity (and perhaps also thanks to my uncanny ability to retain bits of useless information and observations) -I now know the identity, occupation and workplace of the current beau of my ex.
These are things I did not need to find out. Nor have I consciously gone looking for them. Yet they come, unbidden, in my path.
