So far I'm the only Greek in my immediate family. I have an uncle and a couple of cousins that are Greek, but thats it. And my brother has some time to think about whether or not he'll be Greek, since he's only 4!!
However, when he heads off to college in 14 years, I will encourage him to go greek!! By that time, he'll have a brother-in-law who is a Sigma Nu, and uncle who is a Lambda Chi, a cousin who is SAE, and another uncle who is a Pike-so hopefully they can work on him!
