I’m not good at impossible things

I can no more describe you
than I can put a thing for the first time
where it already is.

If I could make a ladder of light
or comb the hair of a dream girl with a real comb
or pour a table into a jug…

I’m not good at impossible things.
And that is why I’m sure
I will love you for my ever.

[Norman MacCaig {1910-1996} 'Sure Proof']
