Sorry if it seems silly, but I have a question:
I sometimes find myself asking if I should use "will" when talking about future plans.
For example: "We'll talk about it later today, when 'we/ we will' speak on the phone."
Using "will" in this case sounds clumsy to my ears. But the person is talking about something that will happen in the future, so I see no good reason to omit it.
So, what is the right grammar here, and why?
