When I started my meal, ...
When I checked my emails after my holiday,...
They didn't know what to do...
The flat was dark when we got home...
When she turned on the TV...
Yesterday I found some old pictures...
because we'd forgotten to leave the light on.
everybody else had already finished.
I saw that I'd received over 200!
which I'd drawn when I was a child
the programme had already started.
because the hadn't listened to the instructions.
