I asked my teacher what I should do next.
I don't think children should drink beer.
It's raining, so you should stay at home.
I guess we should go get something to eat.
I think you should think about the future.
You should have left half an hour earlier.
I agree with them that we should try again.
Could they tell me which way I should go?
How much food should I be feeding my cat?
How often and how much should I feed my horse?
Do you think that handguns should be made illegal?
Do you think I should go by myself?
Where should I put my baggage?
Should I reply to her letter?
What should I do now?
Should I talk to you?
