I wondered if, in the future, when I don't wish to take your call, would you have thought back to the past moments?
Of the many times I wanted to talk but you were somehow not in the mood; busy; inconvenienced; etc, to chat?
And of that single time you actually even gave me a long-distance call, but I refused to pick up?
Sometimes, by the time you're ready, you no longer have the opportunity to do so.
