Hi there Tom !
Congratulations on the hard work, and on the results you and your students have achieved.

Just to be clear : my point isn't so much about the language allegory being efficient or not in your specific case, as I would be the least qualified person to make any comment on that, having only a extremely limited experience in tutoring myself (explaining software features and 3D concepts to coworkers).

This was just a remark on the fact that just because a concept may seem easier to grasp when presented as an analogy (and without a doubt, your experience shows that it does work), it can also be an hindrance to some audiences : some may straight up not understand the analogy (as I would assume that many people don't even know what nouns and a verbs are begin with ...) ; and some may just be confused by this extra layer obfuscating the information. But as said, for most people interested in MOI this will be easy to ignore anyways.

Thanks for sharing your story !
