I think you're asking when to use am,is, and are? You use "am" when you're talking about yourself. "I am going to the grocery store." You use "is" when you're talking about someone else. "She is talking on the phone." You use "are" when you're talking about more than one person. "They are going to the movies." I hope this helped. :)

that's a hard question.

Huh?
