     When I was a boy every holiday that I had seemed perfect. My parents took me by train or by car to a

hotel by the sea. All day, I seem to remember. I played on the sands with strange exciting children. We make

sandcastles with huge yellow walls, and watched the incoming tide destroy them; we splashed each other in

the water and shrieked with excitement. When the tide went out, we climbed over the slippery rocks and

stared down at the fish and the seaweed in the rock-pools.

     In those far-off days the sun seemed to shine constantly and the water was always warm. Sometimes we

left the beach and walked in the country, exploring ruined houses and dark woods and climbing trees that

overhung streams. There were always sweets in one's pockets or convenient places where one could buy ice-

creams. Each day seemed a life-time.

     Although I am now an adult, my idea of a good holiday is much the same as it was. I still like the sun and

the warm sand and the sound of waves breaking on the beach. I no longer wish to build sandcastles and I

dislike sweets instantly, but I look forward to sitting down to a good meal and a bottle of wine in the evening.

     I think, too, that I prefer spending my holiday abroad. I want to smell different smells; I want to see

different kinds of trees, flowers and birds; and I also want to see people with different colored skins, wearing

different kinds of clothes. Above all, I want to hear a different language spoken and listen to different musical

rhythms from those I am used to.

     But I still need my companions-not, of course, to play on the sands and eat ices with, but to drink with and

talk to on warm moonlit nights.

     Sometimes I wonder what my perfect holiday will be when I am old. All I shall want to do then, I expect,

will be to lie in bed, reading books about children who make sandcastles with huge yellow walls, who watch

the incoming tide, who make themselves sick on too many ices…
