  • You look tired. You should have some rest. 
  • He shouldn’t drive so fast. He’ll have an accident one day. 

I think you should …

We often say I think … should  to give somebody advice.

  • I think you should buy a new pair of shoes for the party. 
  • I think we should go home; it’s very late. 

Note that in a negative sentence, we often say I don’t think… should… (NOT I think… shouldn’t…)
