Dinner was a great success. Thank you all for the kind comments. Yes DJaw, the crossing letters would have done the trick, that is why I find the 'cold-solvers' on"5" so very clever. I'd find it very difficult indeed.
Well Ari, the cops over here would just love to find a motorist doing 5@5 while driving. They have a special reward for them :)
Thanks all for participating.
See you next week (Os 'dan ni'n byw am yr adeg)
Be safe and well
