Homework blues

The son left his homework at school AGAIN. "That's ok mom, " he says. "I can use sister's books." You see, this is a perk of being a twin. Plus the fact they share the same classroom. The problem is, sister never forgets her books, loves to do her homework, and despises having to share with her brother. The father's solution, is to let the son go to school without his homework and therefore after a few zero's he will learn his lesson. "OK" I say, the son pouts back to his room. Later as I am loading the washing machine for the 5th time today, I hear giggles in the brother's room, they are sharing her spelling book and brother is doing his homework. The brother has promised to give the sister one of his webkinz in exchange for the use of her books, and of course, sister gladly hands over the books! Kinda worries me about their bargaining in the future years..... Wonder how many loads of laundry I can get done for a webkinz??????
