I don't have a livingroom. He doesn't have a livingroom. eveybody doesn't have a livingroom. why 'everybody' use 'doesn't'? isn't it don't?

Hi Ms. Choi,

It was indeed a very great question and this is my answer Ms. Choi;

The indefinite pronouns anyone, everyone, someone, no one,everybody, nobody are always singular and, therefore, require singular verbs.
