ending phrase with "then"

[Smiling]

What's the meaning of the "then" word at the end of the phrase or sentece. Or to put it another way - how does "then" modify the meaning of the phrase if I append it to the sentece.

Examples:

See you tomorrow.
See you tomorrow then.


Thank you.

JHi,
Then means in that case, taking into consideration all the facts.
A.- Why don't you drop in for a cup of tea? Come this afternoon.
B.- Sorry, I'm busy today. But tomorrow I could see you after six.
A. -Good! See you tomorrow then.

Regards
