Hi teacher, it´s always nice to have you around.

   Reading the sentences  "Enjoy it while it lasts./  Enjoy it while you can./  Enjoy it while you have it."   I couldn´t help think they have an "order" quality to them, or have a ring of  "advice".

    In fact the poem is more of a wish, the kind of people have when they fall in love.  Indeed, it´s a sort of  "I wish it never ends, however I will plung in it head-on", no matter what...
