I'm not sure if this question is stupid enough, but here goes:
There is a set of skills, mostly in the arts, that are typically taken up as a child and pursued throughout life -- Musical instruments, for example, or art of varying kinds. Hence most beginners are children.
There is a set of people consisting of me that wants to take up skills of this sort (...all of them), but cannot stand being around children. Where can relatively inexpensive beginner-level training in arts-type skills be found that doesn't involve lots of interaction with kids and is available to non-college students?
If you are okay with paying, you can always find one-on-one tutors. It'll be the most efficient way to learn (assuming good teachers).
This is a thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. The previous "stupid" questions thread went to over 800 comments in two and a half weeks, so I think it's time for a new one.
