Hmmm. What does this mean?

Remember my post about Robert? I told you that every time I had visited this McDonald's for three and half years, he was there. Well, since the day of my encounter, I have been in there six times. Not once has he been there. I asked Shaun, the kid who works there, about him. He said nobody's seen Robert. I hope nothing bad has happened to him. But I gotta tell ya, this kinda spooks me.
