Undeleted, deleted, undeleted,
I would like to request this question be undeleted.
Shortly after I wrote an answer, the asker commented on the answer, and then deleted the question without explanation. I voted to undelete and also flagged the question, and then a moderator (Jyrki Lahtonen) undeleted the question and explained to the asker why it is rude to delete an answered question. But then the asker deleted the question again without explanation, and then asked a follow-up question separately.
If there is a duplicate question somewhere, then I am fine with closing the question as a duplicate (rather than deleting it), but I was unable to find a duplicate.
Also, if I have handled this situation poorly (e.g. answering a question instead of giving hints, or insisting on undeleting a question), please let me know and I will try to correct my behavior.
