Postcards - from a place next to you

Perhaps, one of the most romantic thing one can do, for a wife, girlfriend, loved one, etc... is when you're on a trip to a faraway place with that special someone, write a postcard to her (unknown to her of course), telling her how much it meant to you to have her sitting next to you in that faraway place, and send that postcard home... So that long after your plane has brought the both of you back home, the postcard will arrive unexpectedly one day, be tenderly turned over by her with excitement, and warm her heart to no end knowing that every step of the way, she was on your mind, and that she has taken the right path with you...
