I go back, I get back, & You come back

[Jennymendoz]

Is "come back" for 2nd and 3rd persons only?

I'll go back.
You'll go back.
They'll go back

I'll get back
You'll get back
They'll get back

You'll come back
They'll come back

[Thredder]

I'm going today and I'll come back tomorrow.

I'll go back today and sort it out!

I'll get back late so don't wait up for me.

no, perfectly acceptable in all persons...

[Jennymendoz]

Oh I mean if the two persons are talking over the phone

I'll go back there

you can't say 'I'll come back there

[Jennymendoz]

I could say "I'll come to you"
but "I'll come back there" is wrong

I was thinking that "come" means come here from somewhere, unless there is a word "to" (come to).
"Come to" means going to somewhere else.

[Beeesneees]

I'll come back there can be correct, (even in a phone conversations) if one person has been to the place where the other is, and is confirming that he will return to that same place.

You left your work here.
Yes, I'll come back there and pick it up before I go on to college.
