Oh boy, I'd be pretty mad if I drove two hours with my parents just to be more or less stood up! That sounds similar to my last meeting with my friend -- she was late because she was hanging out with her boyfriend, showing him her old haunts. He went back to the car 'for a nap' 15 minutes after they finally turned up.

I am noticing that if I don't really want to see someone, I use the vagueness as an out. If this was someone I wanted to see, I'd have nailed down a time and place already.
