If you're mad with someone and nobody's there to fix the situation... 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 still love a person that you think has forgotten you... 
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.  

If you really have friends who you appreciate... tell them. Maybe they appreciate you as well. That if you don't and they leave or go far away today, tomorrow can be too late. 

                 If you love your parents, and never had the chance to show them... do it. Maybe you have them there to show them how you feel. That if you don't and they leave today, and then tomorrow can be too late.
