You know it's not going anywhere...... when he never drives over 30 mph, hunches over the steering wheel holding on with a death grip and staring at the road ahead with the look of a rabbit caught in the high-beams.
... when he's nice to you, but *not* nice to waiters.
... when he proposes on the *first* date!
Comedy films are also a good water shed - if you laugh at the same bits, you're on to something. If not ... cut and run.
