I have been with my wife for 37 years now so would be really rusty at this.
However I thought I would share with you the best line I have ever heard.
I was sitting alone on a bench at the Pitch and Putt in Birchington and this lady (old) came and sat down beside me. She then proceeded to ask "I hope you do not mind me sitting here" which I replied "No, of course not" Then she said "Please will you talk to me, I need to test out my new hearing aid"
I would have pulled but my wife, mum in law and grandson reappeared 10 minutes later!
Perhaps it is a line TC or Steve can use in future?
