You're far away from the one you love, and you would like nothing more than to give them a kiss. Or, there's a friend in your life who's in need of a hug, and you're not with them to deliver it. Regardless of the situation, a card letting a friend know that you're sending hugs & kisses from afar is a great way of brightening their day and reminding them that you're there for them. Until you're there to give the real thing, a card is a perfect substitution.
