Just believe me (or figure out for yourselves): He can...

.... because he isn't.

I'll draw a picture today, to illustrate what's going on with that warped
spacetime. I thought you should know about that, if only for the sake of your
nick ;)

The key to understanding is that a second is not a second. Delta-t is not
universal (just like distance isn't), but rather depends on the frame of
reference.

Likening some time dilation effects to "after-image" effects may make them more
"digestible" to laymen than having them try to imagine how a second cannot be a
second, but it's not *precisely* what's going on.
