“Don’t cast a clout ‘till May is out” is something I can remember from my childhood days. The word “clout” means clothing.

I must admit that my thermal vest, my fleece lined shirt and my woolly jumper are already making it a bit hot in April. I will probably be cooked alive if I have to wear them throughout the month of May.

Obviously nobody anticipated the onset of global warming when these proverbs were first used.

“Be a hero, go for nett zero”
