The Towel

Mark came home late Saturday night from his friend’s house and entered through the back door into the kitchen and noticed his mom talking on the phone. He immediately noticed that she had a towel wrapped about herself. “Hi, mom,” he said as walked in.
“Geez, you’re home early,” she said.
Mark looked at her. “What, mom!? It’s after ten.”
“Is it that late already?” Mark nodded as his mom said her good byes to her phone friend. “I’ll call you again, Mabel. Good bye.”
As she hung up the phone, she looked at Mark, “You’d better go up and take your bath.”
As Mark left the kitchen he kissed his mom on the cheek and went upstairs. Upon arriving in the bathroom he started to run the faucets and stripped off his clothes. Since his mom was downstairs, he didn’t bother to close the door. He got into the tub and started to soap himself.
A short time later, Natalie came upstairs. She stopped by the bathroom door and asked, “Mind if I comb my hair?”
“No,” Mark said looking at her, “go right ahead.”
She entered the bathroom, looked at him, and smiled. Then she rummaged around. “Now where did I put that brush anyway?” She looked about the bathroom and noticed it on the high back shelf of the tub. “Oh, there it is!” she exclaimed, “It’s on the tub shelf.”
“I’ll get it for you, mom,” Mark said as he started to get up.
“No, that’s okay,” she said, “I can get it okay.”
As she stepped up on the tub edge and reached for the brush, Mark accidentally dropped his soap.
