There are two types of gift-giving in my little, psychotic world.  On "Occasions" (such as Christmas, birthdays, and Valentine's), which are when gifts are given to people who should matter, and "random, stealth-gifting," when is when gifts are given to people who actually do.

Obviously, there is some overlap, since some gifts on Occasions are also given to people who matter.  But random gifts are almost never given to people who don't.
