When first read “class”, I imagined you annotate classes in programming with comments as “@see https://redd.it/…”, which is what I do for any related crucial enough context, including StackExchange, repository sources etc. Yet, in your case, you meant classes in schools/Universes/etc. which is a marvel… Children learn from examples mostly, and your examples are crucial… Thank you… Thank you heartfelt… for teaching children, people accountabilty and respect towards others’ effort and the history…
