Teach NPCs skills

[morthein]

Is your feature request related to a problem? Please describe.

The NPCs have an option to teach you things, why can't you teach them once a day too?

Describe the solution you'd like

NPCs can learn when you read to them, learn from a book themselves, or they watch you enough. Why can't you also just teach them so they jump up in skill like they can teach you?

Describe alternatives you've considered

It would be nice to be able to teach them until they reach the next level, just like reading to them, instead of a bulk once-a-day session like they teach you.
