We have talked about Greek life with our kids since they were old enough to understand words! As far as they know, being Greek is a natural part of college, like living in the dorm or going to football games (and going to class...

of course!).
Of course, I will not force them to go Greek, but they will know all about it when the time comes. My daughter has a few articles of clothing--in fact today she is wearing a lovely pink shirt with green script embroidery that says "Delta Zeta Legacy" on it. Whenever one of my sisters has a baby girl, I give them a bib or some other keepsake that says something similar. My sis-in-law is a Tri-Delt, and I suspect she would like to give Anna some things with dolphins, etc., but I think she is afraid of stepping on my toes--on the contrary, I think it would be great! Because as much as I want Anna to be a DZ, I want her to know that it is her choice, and the more exposure she has to different organizations, the better!
My son has never had any LXA (his Dad & one uncle are LXAs) or ATO (2 uncles) paraphrenalia, but he knows what it is when he sees it.
Edited, because punctuation is good.
