To cake or not to cake?

I saw the sliver of rainbow cake

Stuck to your silky beard.

I saw the growing inches

under my wavering belt.

I saw "us" going downhill

when the cake I managed to steal.

The spring seems to be over and

The birds would sing "deciet".

It was, of course, your birthday

and the crumbs lay on your beard...

Would cake do us part or death?

It's time to put our holy ties to a test.

And oh! like a frenzied freak,

Did I leap for the blessed piece of cake.

The rest remains history and

an icey one at that.
