Edna's Weekend
This is Edna Shaw. She's a language student at London University, so she's got a
lot of university work to do during the week. In fact, she doesn't have any
spare time on weekdays. But when the weekend comes she tries to have a good time getting some exercise and fresh air and entertainment, too.
She spends Saturday morning doing jobs around the house: cleaning the room, doing the laundry, going round the shops. She doesn't have lunch at home, she normally
goes out for lunch with her friend Nancy. As a matter of fact, Edna and Nancy rent a
small two-room flat in the town center. After lunch the girls play tennis or go for a run
out into the country. Edna's got a second-hand Volkswagen which she bought very
cheap.
Saturday afternoon is the time to play sport but in the evening the girls sometimes
go out to listen to a band. Bars are very much like clubs, the music is free and everything
is very relaxed. It's great to listen to some music and dance.
On Sunday the two friends have a nice quiet morning reading newspapers over a
cup of coffee. Sunday is the day when Enda goes to see her parents. They live in a nice
semi in a suburb of London. Enda drives there for brunch. (Brunch is breakfast and lunch combined. It's becoming very popular to have brunch at the weekend.) Brunch is a
good time for all the family. They get together and eat brunch. It's normally a huge meal.
You have all the breakfast things and all sorts of salads and chicken and pies and lots of
fruit. A lot of people go out to a restaurant for brunch. Not the Shaws ... they enjoy theirs
at home.
On Sunday evening Edna and Nancy quiet down a bit. They watch a little television
or, perhaps, have a little chat and share the impressions of the day. It's time to get ready
for Monday. So they usually go to bed early
