Thanks everyone,

By sharing my experience on the forum I've turned an upsetting thing into something that I can laugh about!

Now that can't be bad. And the concensus of opinion seems to be - don't get involved. Thanks for all the replies.

I'll try Songbird's 'friendly wave and keep moving' suggestion. The guy does live across the park from me, so it won't be too long before I get to start that 'assertiveness training'.

Cheers, e

PS - We get 'Seinfeld' here on cable, and I've noticed that the characters are always tripping each other up, and getting into messes. I'll watch the programme with a new interest after my own 3d experiences.
