Logical, in all seriousness -- for the moment anyway -- you are absolutely right of course. Oddly enough, I recall my school chemistry master rather forcibly making the same point. And that was a long time ago.
Called back from retirement to teach our 1947 class, Mr. Waddington ('Bill Wad' behind his back) was the ultimate pedant.
On one occasion, he turned up a little late and explained to us that there had been a little incident on the bus. Apparently, he had absent-mindedly torn up his ticket and the problem started when an inspector came aboard -- Bill was of course unable to produce a ticket.
The inspector was having none of his explanation.He ordered Bill to pay the fare again, with a fine added for 'wilfully destroying' a ticket.
Bill was having none of this either. His defence was that matter cannot be destroyed, but can only be converted into another form and launched into an exposition on the subject.
At this point the inspector stopped the bus and summoned a passing constable . . .
