We say should do something / shouldn't do something when we recommend or do not recommend to do that, when we express that it is a good or a bad idea to do that. "Should" is less strict than "must", it is a recommendation and not an obligation.
Remember: should + infinitive
We often say I think ... should … I don’t think … should … Do you think … should…?
I think you should change your job.
I think I should buy that phone.
I don't think you should care about it.
I don't think Richard should study abroad.
Do you think I should apologize?
Do you think we should call a taxi now?
