Why Guess??? Wishlist instead...
Don't guess what somebody wants.

I remember the days where I would sit down with a JC Penney or Sears catalog and circle all the things that I wanted Santa to bring me for Christmas.  I'm sure my good ol' mother would search through those pages and note what was reasonable (I never did get that Bigfoot Powerwheel).

Nowadays there's a much easier way to find that which your giftee wants.  Sites such as Amazon.com have WISHLISTS.  Even better than getting somebody what they want is being the only person to get them it!  If you buy from the site, like Amazon's listed above, is that the item dissapears from the wishlist.  Buying a gift that is guaranteed not to get returned is ideal!
