Inspired by Dan Pearce's candor in his recent post "An Open Letter To Ye Who is Always Late" which espouses on chronically tardy (read: disrespectful) people, I have a similar rant: "Wanna go to the zoo on Wednesday afternoon?"
"Um, you want to join us or you don't want to join us?" "We'll see." Maybe. We'll see. I'll try. Not sure. I'll see if I can make it. This is called the Next Best Girl Syndrome. Commitment-phobes are constantly in a state of flux.
