Harry：Ooh, speaking of keeping busy----
I have an early start tomorrow,and the baby-sitter has to get home.
[He starts to put on his jacket.]
Where did the time go? It's midnight.
Thank you,Susan. I had a nice evening.
Susan：Me, too, Harry.
I found an answer about the difference between "go home" and "get home" here.
I want to know if I can replace the get here with go, is it still logical?
Say I'm at a person's home and I'm going to go back to my own house, should I say I have to go home or I have to get home？
