L15-1：Fifty pence worth of trouble
Children always appreciate small gifts of money.
Mum or dad,
of course,
provide a regular supply of pocket money,
but uncles and aunts are always a source of extra income.
With some children,
small sums go a long way.
If 50 pence pieces are not exchanged for sweets,
they rattle for months inside money boxes.
Only very thrifty children manage to fill up a money box.
For most of them,
50 pence is a small price to pay for a nice big bar of chocolate.
My nephew, George,
has a money box but it is always empty.
Very few of the 50 pence pieces and pound coins I have given him have found their way there.
I gave him 50 pence yesterday and advised him to save it.
Instead he bought himself 50 pence worth of trouble.
