周末儿子给邻居溜狗，大概溜到林子里去了。回来后，他让俺查查头上是否有 tick 。 Tick 没找到，却觉得他头发像是有些日子没洗了。
问他： Did you wash your hair yesterday ？
儿子很干脆： Nope.
立刻命令： Wash it today!
儿子拒绝： No, I want to wait for few more days.
老妈跳起来： Why?
儿子诡异地： Just want to see how it feels like without washing it for two weeks.
老妈： You smell like chou doufu! 
再威胁威胁： You will be kicked out of school soon!
儿子： No way，it's an all-boy school，nobody cares. You know I even got away with wearing the same shirt 5 days in a row once.
儿子说，不洗头，不换衣服对男孩子来说是件很酷的事。
Boy, oh boy! 俺 faint....
