We can say:
- We have already made the decision.
- We have already been learning English for a half of a year.
Thus, I may use "just" either with Present Perfect/Past Perfect and Present Perfect Continuos/Past Perfect Continuos? For instance:
- We have just talked about you.
- We have just been talking about you.
Futher to the above, is it necessary use "just" with Present Perfect Continuos or it is obviously that the actions is going on at the moment of saying this remark?
