As I buy many records from Australia, I have an Australian friend who collects all the records bought there (I live in France) Today I received an email from my friend, he wanted to know if he could send them now (as he had a lot of). I answered "yes" and wrote:
I hope it has not been taking/ has taken too much of your spare time."
What is the best solution? I thought present perfect continuous was better because it is ongoing situation. May be taken present perfect simple is better as "too much" could be equivalent to a quantity (as in the sentence I have written 6 letters this morning) but I want to emphasize the continuity of this action.
