A Box for Boxes

As odd as it may seem I needed a box for some boxes today.
After all this time I have finally unboxed everything from my last move.
Still...it seems odd to keep boxes when nothing is in them,
Yet I know the day will come again to move.
So therefore, I must box up some boxes and store them away.

Some I will flatten out to store most in a single box.
Others will remain as they are since they are so small.
Sure does seem odd to keep boxes for a rainy day.
But who knows, I may need them for something else.
Alas, those boxes within those boxes will be used someday.
