Wikipedia tells me that Serendipity means a "happy accident" or "pleasant surprise"; specifically, the accident of finding something good or useful without looking for it.
Seems like I have seen this happen about a zillion times in Life, but every moment it happens seems uniquely cool. Makes you wonder about chance, a master plan, karma, or accidental surprise, whatever you might call it.
Driving back to the office today on Calumet in Valpo, I get a text from my wife asking me if I am up for a date night tonight, at the very minute I am driving past Schultz Floral which is displaying this sign telling me Flowers Make Life Happy. Being incessantly impulsive and jacked for a night alone with my wife, I of course reply yes and pull into Schultz to see what they have. The nice girl there shows me this little unique arrangement that is cool and a little off-normal. That is how I like things and luckily my wife must feel the same way.
Call it whatever you want - but I'm calling it LifeEnDipity.
