     Mother's Day and Father's Day are two big national. holidays in many western countries. And it's
interesting because they are not the same in every country. In England, Mothering Sunday is in March.
In America and Germany and other countries, it's one Sunday in May. Father's Day is in the middle of
June. How do you celebrate Mother's Day and Father's Day? Let's learn something more about it from
the following introduction.
        In England, we call Mother's Day Mothering Sunday, because it's always on a
Sunday. I don't really know the origin of it but I remember that my mother had a
cup of tea early in the morning. And then we would go to church. And at the end
of the church service, the children would collect a daffodil (水仙花) and take it
back and give it to our mother who would normally be sitting in the service in the
church. And really that's all we did to celebrate the day.
          As Ann said, I remember taking cups of tea to my mother. The idea in general is
that the washing-up would be done; perhaps some cooking would be done on Mother's
Day. We would try to relieve her of all those jobs to make it a special day for her, so
that whenever she looked around, there was something to eat, something to drink, or
something to read, or something interesting for her to do.
