Red Flag"Call Me Back in 15 Minutes Guy"

I was having a dinner party and I invited my Hawaiian Kite surfer buddy Lou to the dinner, who told me to call him back in 15 minutes.  I called Lou back to invite him to the dinner and he said call me back in 15 minutes. Of course I call him back because he's so cute:) I called him back and he repeats the same thing Call Me Back in 15 minutes.  Red Flag.  There's nothing to call him back about either come to the dinner party or if you are busy no problem.  I can't keep calling someone back.  I have no follow through or time:)  Good Times.  Call Me Back in 15 Minutes Guy.  Red Flag.
