is when you're meeting your mate somewhere, there's no one else in the road, and you can seem them approaching. You just stand there looking at them walking towards you from miles away. Or vice-versa. It becomes awkward once the other person has come within a range close enough for you to mentally confirm that they are the right person, and then the person that's already stood there doesn't know whether to go out of their way and walk towards the person that's arriving, or just stand there and watch them slowly but surely make their way towards them.
