Millie, can you go to office to bring me the chair?
Where’s Millie? She is on the way to the office, or maybe she is in the office.
She has gone to the office. And she will come back in a few minutes.

Mr Dong has lived her since he was born.
Some verbs, such as come, go, buy and leave, can be used in the present perfect sense, but they cannot be used with for or since in positive statements.
