Should or shouldn't

Listen to that music! Our neighbors ___________ play music that loud at this hour.

If your tooth is still hurting you tomorrow, you __________ go to the dentist's.

Cathy __________ keep ringing her ex-boyfriend. I think he is with another girl now.

Before going to Paris for your holidays, you __________ try and learn something of the language. You will enjoy things a lot more.

You ____________ always knock on the door before entering. This is a private office.

We ____________ bring something to Kate's party. I'll feel really embarrassed otherwise.

That model on the TV is too skinny. She __________ eat more, I think!

Lizzie __________ ask Bryan to help her with her studies. He did the same course last year.

Pregnant women ___________ smoke as it can damage the baby.

We _____________ leave too late tomorrow if we want to reach the beach before lunch.
