Charlotte Makes Making My Bed Difficult

I was just putting clean sheets on my bed when my cat Charlotte took notice of what I was doing. I knew I was in trouble.
Soon enough, she was under the covers.
"It's so dark under here!"
"The sheet is too straight. Let me mess it up for you!"
"Okay, I'll get out of your way. Sorry. I was just trying to help. It's my bed, too."
