complaint

The match could be on the other channel. Why don't you look?

He could have got out through the bathroom window.

He could well be late - he usually is.

Shiela's in the office - she could do it now.

She could speak French pretty well, I recall.

She could have told you he was her boyfriend's father!

Could I take 5 minutes of your time at the end?

If you are late back from work, I could leave it in the oven.
