cant agree more to this ! in fact, here in mumbai, many of such training-schools/classes or of other creative things, esp. where elder people are in majority, they are conducted on weekends in the morning, or in early mornings/late evenings on weekdays. atleast this is applaudable that inspite of remaining so busy in this rat-race, some people still have a burning desire to devote time and learn new things.
even the wing chun school i was telling about is one such school, and one other escrima school that conducts classes only on sunday mornings that i know of. there are such few others too.
