The question has been closed after 5 users voted to close the question, which is the higher number of users required to close a question; it has not been the decision taken from two users.
In both the cases, if a question has been wrongly closed, 5 users (or less, if one of the users is a moderator) can vote to re-open the question; the OP can vote to re-open his/her question too.
Begging any of the users who closed the question to re-open it is needless; any user who can vote to close a question can also vote to re-open it (and they don't need to be the same users).
I would say don't say anything. If you think that effectively the question should have not been closed, or you changed your mind (e.g. because you are now giving the question a different interpretation), then you can vote to re-open it.
