Playing around with Time
One thing bothers me a bit about this, I get the mail box was some kind of Time portal of sorts, but shouldn't more people have discovered it?
Eventually, Alex & Kate would have either moved from The Lake House, sold the property, or died. Wouldn't there have been a really good chance the someone else mail from the future would have ended up in there?
Weirder, but what about bills or other stuff sent to the house? Anything which ended up in that mail box could technically travel to any time the mail box existed?
Granted this is a minor flaw, but it still bugs me a bit. Otherwise, The Lake House was a good 'time,' no alcohol required.
Hope Jeremy Jahns doesn't sue me for bothering his line just once.
