Real rain drumming on the roof, calming you, or waking you up. Rain that sprinkles itself down on you as you run, catch drops in your mouth. Rain in your head “too many noises too many sounds”:
Stress.
Rain that makes you sad and washes all hopes away, cancels a game or cancels a thought.
Ignore them, let your mental rain drain their comments away.
Ignore them, don’t let them make you stop writing.
Rain that drenches your clothes or your book. That makes you yell out in anger and rush back to your home. Into your family and their loving arms. The Rain wasn’t real, but painful and heart-breaking; imagine a drain and let it disappear.
They have a storm of their own.
