WHEN DO YOU KNOW? I was listening to a debate on radio the other day about when we realise we are getting older,I can remember in my fathers day he and his friends were of the opinion that they had passed their sell by date when policemen began to look young. Only last weekend I had my own thoughts on the subject when myself and a friend called for a beer at a local bar only to find despite the freezing temperature that we looked over dressed. Now I am used to seeing my local postman doing his rounds,winter and summer in a pair of shorts,but young men on a freezing Friday night in shorts and t shirt!! To make things worse many were accompanied by scantily clad young ladies with,to quote a phrase nipples sticking out like chapel hat pegs. Just to clarify for the benefit of those haven't attended church recently,almost all chapels in the UK were as a rule well heated and provided a peg to hang ones hat and coat,hence the reference to nipples on a cold day. Oh yes...
