Since you used 'since it opened', that gives it a finish, but 'since 1987' leaves it unfinish. I do agree to 'since' being contradictory...
I am sorry you said that. You must be aware that Cas and I are talking about the other part of Since, the part we use Present Perfect.Originally Posted by Neurotica
If you insist, we may change the question for you like this:
“She has visited Ocean Park for three times since 1987.”
It still looks like a finish to me, do you agree?
