After a busy day he settled down in his train from Waterloo for a nap as far as his destination at Winchester. Just then the chap sitting near him hauled out his mobile and started up:- "Hi darling it's Peter, I'm on the train - yes, I know it's the 6.30 not the 4.30 but I had a long meeting - no, not with that floozie from the typing pool, with the boss. No darling you're the only one in my life - yes, I'm sure, cross my heart" etc., etc.
This was still going on at Wimbledon , when the young woman opposite, driven beyond endurance, yelled at the top of her voice,
"Hey, Peter, turn that bloody phone off and come back to bed!!"
