Should I use "We then" instead of "Then we" [closed]

Solution 1:

Both are fine, but when you begin a sentence with "then" as a transition from a previous clause, it normally has a comma after it:

We listened for about an hour. Then, we left.

That isn't needed if you are not beginning a sentence:

We listened for about an hour then we left.

If it is not indicating a succession of events and is instead being used to mean "therefore" then the comma is not necessary, for example:

Waiter: "Are you intending to eat here?"
Customer: "No".
Waiter: "Then I must ask you to leave".
