When my mother came home I was watching tv.
While the water was boiling she washed her hands.
My brother was playing footbal when it started to rain.
We looked at him while he was drinking his beer.
While the wind was blowing she decided to go for a wald.
When I arrived home my parents were having dinner.
You were eating apples when your father came in.
John was doing his homework when I phone him.
While they were cooking in the kitchen their mother just popped in.
While I was reading my brother started crying.
