The older the better

An old greyhound trainer ordered a coffee and  sat down in the café at his local track, still carrying a lead, a kennel jacket and a muzzle . As he sat drinking his coffee a young woman sat down opposite him. She turned to the trainer and said “are you a real greyhound trainer ? “

He replied “ Well I’ve spent my whole life training greyhounds, started on the flapping tracks, moved to Park Royal and then White City, then went to Ireland, trained a Laurels winner, came back up North trained a good a few at Brough, then Rye House, Catford, the Stow. Won an English derby , employed over two hundred kennel hands, won over half a million for my owners over the years and won trainer of the year three times, so yes I suppose I am a real greyhound trainer, and you, what are you ?
The woman said “I’m a lesbian. I spend my whole day thinking about naked woman. As soon as I get up in the morning, I think about naked women. When I shower. I think about naked women. When I watch T V . I think about naked women. It seems everyting makes me thnk of naked women”
The two sat sipping in silence.
A little while later a young man, came into the café and on seeing the muzzle and lead sat down on the other side of the trainer and said “are you  a greyhound trainer ?”
The old man replied “well I thought I was, but I just found out I was a lesbian”
