Step-by-step explanation:
"Should" is a modal verb used to express suggestion, recommendation, or even obligation, although lightly. As a modal verb, it stays the same no matter the person of speech being used with it: "I should, you should, he should," etc. Also, the verb that follows it should NOT be preceded by "to": "You should go."
In the negative form, "should" can be contracted with "not", becoming "shouldn't". In the interrogative form, it comes before the subject of the sentence. Take a look at the examples below:
- I should stop eating so much fast food.
- You shouldn't talk to your parents like that.
- Should I call her one more time? No, you shouldn't.
