Well,in this case and when I was speaking about lesson -which I put with a question mark,because it could be ambiguous-I meant that the ending could teach us to love,simply.To take profit of every moment we have with the beloved person without denying the reality,because it'd be to deny ourselves.To be true to ourselves and to this person; to live every single moment as the last one;to fight for what we wish,no matter the efforts;TO BE OURSELVES,in short.And I meant also that a happy ending wouldn't have this sense of redemption in Ennis figure that,unluckily,now has.Even if,I repeat,I would like a happy,conventional and loving ending...
