Is the correct abbreviation of administration below admin. or admin'? I think it's the latter, SWMBO [1] thinks it's the former. Please tell me I'm not wrong again. "I had hoped for both meetings to be on the night of the 12th and wonder whether this could be an admin. error and my appointment with you is in fact on the 12th?" or "I had hoped for both meetings to be on the night of the 12th and wonder whether this could be an admin' error and my appointment with you is in fact on the 12th?"
