Why would the P site and not the A site be the first one to be occupied by a charged tRNA during translation initiation?

During initiation, the first charged tRNA (loaded with methionine or fMet) occupies what becomes the P site when the ribosome is assembled. It never sits in the A site, although every subsequent tRNA does first sit in the A site.
