"Eh mom, could you come here please", Luke asked with a fatigued tone.

"Yes sweety, what do you need ?", his mom asked as she came in the living room.

"Yes, of course i'll help", she reponded, "hmm, let's see, oh my, i don't, what?", she said as she was unable to figure out the homework. "sorry sweety, but i can't help you with this". she admited.

"Don't worry about it, but in that case, could you get Natalie to help us, i know that she can help us, she was good at math, didn't she", replied Luke.

"Well in that case, i'll get here right now", his mom replied as she went upstairs.

"Why did you tell your mom that , if we don't have that homework ?", Commented Josh. "It's all part of surprise, just wait", Luke replied.

Meanwhile In the second floor

"No, i will not come down", Natalie yelled.

"Yes you will, Luke needs your help", her mom replied.

" I can't do it as i am, especially as his friends are here", she argued.

"C'mon it will be quick, and besides, i'm your mom so i need you to obey me!", her mother exclamed.

"I don't wanna", pleaded Natalie, as she didn't want to let Luke's friends to see her naked.
