They Grow Up So Slow

So I now have a one week old son, and I can't say that I agree with the popular observation that children "grow up so fast."  I think they grow up really slow.  At best, they grow up at an average speed. 

For example, I saw a mother at the supermarket yesterday talking with someone about her kid.  "He's already 7, can you believe it?" She said.  "Man, they really grow up fast don't they?"

No.  They don't.  It took SEVEN YEARS for him to get to that stage.  Michael Phelps had time to win 14 Olympic gold medals in that time frame, there's been two presidential elections, New Orleans was destroyed and rebuilt, and world peace started and ended in that time (ok - we wish that last one was true).  And the kid is still not even half your size.  They grow up slow.
