Grandpa's Chocolates

My little brown box, not mighty, merely small,
my little brown box holds almost nothing at all,
it holds but my dreams, my wishes, my thoughts,
to open and discover would require much force.
Its chipped edges are mine to stroke,
the feelings I get aren’t something to provoke.
To caramelize my heart is to build this box.
Shhhh it's a secret: it's full of chocolates.
