Thanks alot masaegu san. Could you kindly check my translations (especially 2, 5, 6, 8), too?
I have no idea what number 7 means, and also I am kinda confused when it comes to sentences number 6 and 8 because I don't know when "治っ
たら" means "when", "if" or "after".
Usually I would prefer to use "たら" for "if" and "あとで" for "after". Can't remember the alternative for "when", though.
