All to say, from what I have observed, not all vegetarians and vegans are compliant, and especially not when it’s someone else’s conviction. If you did not see the child eat the hot dog, then the person who saw it happen has a decision to make. Of course, it sounds like they chose to tell you about it. This is not your problem, but it will certainly be theirs for as long as they try to enforce this with their child. You provided a vegan meal, and did not serve the child a hot dog. Beyond that, you cannot be responsible.
The fact that the text is partly in German excludes almost totally that the text was written in France or by French people. French was fashionable in intellectual circles throughout Europe, whereas the use of German was almost totally restricted to the German-speaking part of Europe (today’s Germany, parts of the Austrian empire and Switzerland).
It would take very long to prepare the wood, it’s also very labour-intensive, the resulting structure will (as the original) be heavy and a fire hazard. Other cathedrals have received lightweight steel roof structures without anyone complaining so this is probably the way to go, especially if it should be completed within the announced five years.
The possibility that the fire was the result of arson cannot be dismissed. Barely an hour after the flames began to rise above Notre Dame — at a time when no explanation could be provided by anyone — the French authorities rushed to say that the fire was an “accident” and that “arson has been ruled out.” The remarks sounded like all the official statements made by the French government after attacks in France during the last decade.
In 1905, the French parliament passed a law decreeing that all the properties of the Catholic Church in France were confiscated. Churches and cathedrals became the property of the State. Since then, successive governments have spent little money to maintain them. Those churches that have not been vandalized are in poor condition, and most cathedrals are in poor condition, too. Even before the devastating fire, the Archdiocese of Paris stated that “it can’t afford all the repairs” that Notre Dame needed, “estimated at $185 million.”
The child will probably say something about the tasty treat if he doesn’t know he is being raised vegan. That will give the parents an opportunity to explain their convictions. Or he knows exactly what he did, in which case the child is also old enough to confess on his own. There is no definite timeline. It depends on how quickly he can make her fall in love with him. That in turn depends on her susceptibility.
