Where has my lid gone??

Oh plastic lid, where could you be?

Why you have left me, I cannot see.

The others, they tell me they know my plight;

I need you to cover me and hold me tight;

I need you with me, morning, noon and night.

Please return to me, my lovely lid;

Please protect my insides, as no other lid did.

So here I sit, waiting for your return;

My lovely lid, who protects me from freezer burn.
