Time Travel - yep, sure is possible

I'm off to Hawaii tonight at 6pm and will arrive at Honolulu at 6:45am. Same day.

It's a 10 hour flight (groan... hope they've got decent movies) but I'll end up arriving before I've even gotten out of bed. Which works out well for me because I'm awfully forgetful.

*ring-ring*
"Uh, hello?"
"Hey, Marty man, sorry to wake you."
"Who's this?"
"It's me--well, us. I'm you."
"Huh?"
"It's Hawaiin Marty here."
"Huh?"
"Listen, I know I don't exist in your world yet but by some quirk of the metaphysical, I've found a way to call you."
"Huh??"
"You've forgotten to pack your underwear. Don't forget your undies when you pack today-"

Yeah, something like that. Though if you look closely it all falls apart...

I always leave packing til the last minute and then end up having to rush. Maybe I should go do so now instead of wasting time writing nonsense here...
