Cliff, I had understood the optician joke, saw and noted the smilie and am with Jim in knowing that you didn't mean to cause offence - I just couldn't pass up the opportunity to tease you and Morgan.
Meanwhile, I see from the Members list that r1wigs has packed his bags and left, and agree with Jav - it seemed to me that he was either very sensitive about something, or was looking for something to take offence at. As Terry Wogan keeps saying, there are too many people out there just waiting to misinterpret and get upset about innocent comments. Combine that with your sig, Cliff, and it's a wonder there are so many of us here getting on so well. :S
Time to move on. How are your tomatoes doing, Morgan?
