Curtains

During the day, I'm the ultimate bodyguard against UV rays, Sticking tight to block the sun's passionate flames. My owner sleeps soundly inside with the AC on, While I'm out here, about to smoke from the heat. In the afternoon, I become a prop for hide-and-seek, Kittens and puppies love to dart behind me. Only a tail sticks out, wagging in the air, Thinking they've perfectly concealed themselves. At night, I transform into a horror movie star, A gentle breeze makes me flutter and sway. Often in the dead of night, I startle the owner, Who's woken up to go to the bathroom, Scaring away all sleepiness and breaking them out in a cold sweat. I strive every day to maintain indoor privacy, But honestly, I have a small wish too – Master, next time you wash me, Could you please not do it like you're washing Grandpa's rag?
