Perfect Gift????

My son has a theory about what gifts are considered "good"ones for birthdays, unfortunately it makes no sense. Apparently the hundreds of dollars in games, skateboards, clothes and shoes do not count. There are times when i am starting to think that his brain has gone on a permanent vacation. His recent rant was about the "quality" of game he gets, and i sit through the whole thing thinking " Keep talking. I always yawn when I'm interested."........
