You fix it.

   Maybe today, that person still wants to be your friend.

   And if u doesn’t, tomorrow can be too late ...

   If you're in love with somebody, but that person doesn't know

   ...tell her/him.

   Maybe today, that person is also in love with you.

   And if you don't say it, tomorrow can be too late...

  If you really want to kiss somebody.

  Kiss her/him.

  Maybe that person wants a kiss from you, too.

  And if you don't kiss her/him today tomorrow can be too late...

    Tell her/him.

  Maybe that person has always loved you.

  And if you don't tell her/him today, tomorrow can be  too late...

    If you need a hug of a friend

  ... ask her/him for it.

  Maybe they need it more than you do.

    And if you don't ask for it today, tomorrow can be too late...

  tell them.

    May be they appreciate you as well.
