Misha: Do you have magical holidays,
Robin? Can you tell me about them?

Robin: Well, where do I start, Misha? I
come from Scotland and my great-grandparents were the Druids. The Druids are
magical people. They can speak to the trees and to animals. They can fly and
see into the future. They say that a year has two halves: a light half (spring
and summer) and a dark half (autumn and winter).

The weather in Scotland is usually cool,
but spring and summer are often nice. It is never hot, but it can be quite
warm. It sometimes rains, but we also get some sun. The nights are short and
the days are long. People work in the fields. Children lie in the sun and play
in the woods.

But
autumn and winter in Scotland are very cold. The weather is bad. In autumn it
often rains and in winter it snows and rains, sometimes
at the same time! The sky is always grey and we rarely see the sun. A strong
cold wind blows. Children don’t go out in the evening. Evenings and nights get
longer and longer and we sit near the fire and listen to my granny’s long
stories.

Then
there are days between these two seasons. They are not summer and they are not
winter. We call them the time of no time. On these days magical things happen
and people can travel in time. One of these days is in spring. On this day we
light huge fires and celebrate the beginning of spring and the end of winter.
It’s a very happy day.

Misha:
I understand. Nowadays it’s like our Easter.

Robin:
You’re right. And we’ve got another special day — 31 October, a sad and dark
day. It is the end of the light half of the year. On this day we remember our
dead. A lot of people are afraid of the dead, so they wear masks and make big
lanterns.

Misha:
How interesting! Nowadays people celebrate Halloween on this day. And they also
wear masks and make lanterns, but they do it only for fun.
