My parents are complete opposites when it comes to cleaning up after themselves.
My dad is the most organized person I know. Everything is arranged systematically--from schedules of bill payments to the way the contact list on his cellphone is arranged. He makes a schedule, and unlike most of us in the real world, he is able to stick to it. When he tells the family that he wants to leave the house at 5:00PM--you better be ready at 5:00PM.
My mom, on the other hand, is... not like my dad at all.
My mom is a woman of many, many great talents and abilities--but being conscious of the time is not one of them. Rarely does it happen that my mom is ready and dressed before my already-outside-dad is honking the car horn, getting more and more impatient by the second. At this point, my mom probably wouldn't have an outfit or bag ready, and would still have rollers in her hair.
Of course, with mom always rushing to get dressed, there's no way that she can clean up after herself before leaving the house. There will always be a light still on or a drawer still open after she closes the bathroom door.
After going out one night, my dad went ahead to their room while my mom was still in the kitchen. My dad found the bathroom in disarray. This time though, he wanted to teach my mom a lesson.
My dad proceeded to turn on all the lights, open even more drawers and cabinets, scatter toiletries all over the dresser, throw clothes and shoe bags on the floor, and even turn the chair over. He winked at me, then went to bed.
When my mom finally got to the bathroom, she exclaimed, " Oh my God! Dad, what happened!?!"
My dad casually woke up and replied, " I don't know! You left it like that when we left!"
To which, my mother retorted, " Of course not!!! These are your shoes!!! "
