Tail him where? I waited in the car in the arrivals section for a good 20-30 minutes before the Airport security person asked me to move. After that I had to rush to a wedding that was not going to happen. Of course I am omitting some information, to protect the privacy of certain people involved, but I have described the actual events as they happened, particularly since I was there.
My friend is an adult and I don’t expect my friends to vanish after I drop them off, do you?
