A friendship can weather most things and thrive in thin soil; but it needs a little mulch of letters and phone calls and small, silly presents every so often - just to save it from drying out completely.
Life... is like a box of chocolates - a cheap, thoughtless, perfunctory gift that no one ever asks for, unreturnable because all you get back is another box of chocolates. So, you're stuck with mostly undefinable whipped mint crap, mindlessly wolfed down when there's nothing else to eat while you're watching the game. Sure, once is a while you get a peanut butter cup or an English toffee but it's gone too fast and the taste is fleeting. In the end, you are left with nothing but broken bits filled with hardened jelly and teeth-shattering nuts, which, if you are desperate enough to eat, leaves nothing but an empty box of useless brown paper.
