And in the evening play a double bass?

Happiness is compulsory at this time
Xmas parties,alcohol and drugs
Inebriated,I can never rhyme
I sit and watch the mating of the slugs

But surely nothing mates in winter  cold
For slugs don’t have a coat like humans do
Perhaps ,despite appearance, they are bold
Need no injections to prevent the deadly flu.

On balance would you rather be a slug
That lives a  life of freedom in the grass
Or do you live  because you write and blog
And  in the evening play a double bass.?

A slug can’t   sing a song nor speak  kind words
This comparison is  foolish and absurd
