People fast during ramadan and then there is one day they celebrate their Eid and eat and enjoy. Similarly there are days in our lives that we focus specifically when they approach specially the wedding anniversery, birthdays, valentines day (my wife is my valentine :)), I try to pay more attention on those days because in our busy lives we don't get chance to make everyday alike. Life is variable, with pits and falls, happy and sad moments, we have 4 seasons in Pakistan, days and nights, changes add value to life.

Just my viewpoint... :)
