Midnight poem

I want to write a poem
That would describe a foam
Or a cat that roamed
on a city without a home

This doesn't make sense
Because I want you to not feel tense
For me to paste letters together
Would mean opening a book made of leather

The bird's nest is on the rooftop
I don"t know why mom called a cop
Maybe for me to stop
Writing the poem that looks like a flop

But I won't come to a halt
Even if I have to start growing malt
Or crash a wedding to catch a dove
For you to see my love
