Meaning of Cousin

Nate is one of the luckiest little boys around because he has awesome cousins.  Now, in Chinese culture cousins are often referred to as extended brothers and sisters and there is lots of complication around between whether it is your father's sister's daughter or son...on and on and on.  It can get pretty complicated quickly but when you dumb it down the meaning of family is defined but what you make it and Nate is lucky to have two older girl cousins that do nothing but cater to Nate's every wish (good thing or bad thing not sure yet!).
