good timing

i normally am on the phone an hour nightly before going to sleep.  last night, i wanted to avoid a certain caller so instead of just an hour, i kept my phone engaged for around two and a half hours.  close to midnight, i stopped it already.  guess what, it hasn't been free awhile and it already rang right away.  it was the caller i wanted to avoid on the other end.  i asked whether he's been calling long.  he said it was his first attempt.  he added he was supposed to call at 10 but got busy so he got to call midnight instead.  oh, so he was spared all the busy tones?!  hmmm... is that a sign or is that a sign?
