How does eliza respond to the following comment by higgins? "at her age! nonsense! time enough to think of the future when you haven't any future to think of. no, eliza: do as this lady does: think of other people's futures; but never think of your own. think of chocolates, and taxis, and gold, and diamonds." she is insulted and tells him she doesn't want any of those things; she is a "good girl." she is tempted and finally agrees to stay for lessons, as long as higgins and pickering keep giving her chocolate. she argues that it is irresponsible for her not to think of the future.
