Since the school days, a non-work task I've somehow always been assigned to has been to remember people's birthdays. (And) so I try my best, to remember all birthdays of the members of the choir, of our kendo club, etc... and try even harder to remember birthdays of people who really matter to me. 

As a child, though I don't come from a wealthy family, I would say my parents did a wonderful job of leaving me with beautiful birthday memories.
