can you say

0I don't think the context is right for "haven't you seen?" without an object. "To see" can be transitive or intransitive, but somehow this one begs for an object.02br

0Hi Avangi, I wonder why you use the simple present when the verb is in the past tense "opened". Could you explain? My guess is "don't you see the opened window" instead of "don't you see I opened it" which is wrong and requires "didn't".0-

0I would like to apologize if my comment sounded harsh. I don't know whether it sounded offensive to native speakers and others or not but I had no intention to offend anyone if it did. That's a reason why I'm working hard to improve my command of English. 0-
