When I saw you in the park you were sitting on the grass 

while I was having a bath you came in 

When I was reading a book TYhe lights went out

While you doing your homeworkshe call me

When I was waiting for you an accident happend

2 3 2

when you're tired, don't drive.

While I was waiting for the bus, it began to rain.

While I was playing with the children, he came home.

He called me whileI was driving home.

If you cut my grass, I'll pay you enough to make it worth your while
