     In the USA, Mother's Day is a holiday on the second Sunday in May. On that day, children give their mothers cards, presents or flowers. One of the best ways to celebrate Mother's Day is to give mothers the day off. And other members of the family do the housework, so that mothers can have a good rest. In the morning, Dad and children usually get up early and let Mum get up late. And then they go into the kitchen and get ready for her favourite food. After cooking the meal, they put everything on the plate （盘子） . When everything is ready, they carry the plate and Mum's favourite books or newspapers to her bedroom. They let Mum have breakfast in bed. It is a good day to let Mum rest and let her see what a nice family she has.
