Contentment is the only real wealth.

I am a misanthrope yet utterly benevolent.

Give a little kindness, everyone houses some kind of pain.

This world is all we have.

Spring rain leaking through the roof dripping from the wasps’ nest.

I think every family should have a dog; it is like having a perpetual baby; it is the plaything and crony of the whole house. It keeps them all young.

There are moments to indulge and enjoy, but I always know when it’s time to go home and wash my knickers.
