Friend: "Hi! Just returning your call."
Me: "I appreciate you calling back. Since I left you the message though, the spot has been filled."
Friend: "Procrastination pays off again!"
Update 7/28/09 -- Oops! I was looking at something else and in a skim over this post saw that I said "It was a long time...before she returned the call". What I meant to say was "It was NOT a long time...". My sincerest apologies!!
