On a lighter note, I was reminded of this R L Stevenson poem I learnt as a child when I saw this cow:
The friendly cow all red and white,
I love her with all my heart:
She gives me cream with all her might,
To eat with apple-tart.
She wanders lowing here and there,
And yet she cannot stray,
All in the pleasant open air,
The pleasant light of day;
And blown by all the winds that pass
And wet with all the showers
She walks among the meadow grass
And eats the meadow flowers.
