You can feel the fury rise when someone jumps a queue or pulls out in their car even though it’s your right of way. You can let impatience bubble up when the cashier is beeping your shopping through slowly and you have somewhere to be. You can hold a grudge when someone doesn’t message back, or cancels yet-another meet-up. Or you can take a deep breathe in, growl or sigh it out, let your shoulders drop, fling your arms and legs around; shake off the frustration – and watch the negativity drift away like a grey storm cloud making way for blue skies and sunshine.
