Leave the bathroom happily. You have done the poo, shut the door to contain the smell. Say ta ta to the bathroom now until you meet again. Also say sorry to the bathroom as it has seen you poop hundreds of times. Check that you have no toilet paper stuck to you.
Thank you for reading my tutorial, I hope it helped. Comment any questions or queries in the comments.
P.s Don't ever smear poop on the walls, it will result in sticky hands and dirty walls.
