I have three sons, and my husband is not Greek by his choice. I've talked about my sorority involvement and the boys have watched (and when appropriate, participated!) along with me. Heck, I was pregnant with my youngest while a Chapter Adviser and he came along with me to functions until he outgrew the confinement of a baby carrier.
I also sang AOII songs as lullabies, they wore "My Mom's an AOII" tees when younger, and I hope when the time comes each of them considers Fraternity Membership. We've got about 5 more years before I'll start the "Carnation Nation Consider Fraternity Life Program"
I have a niece who's a sophomore in High School. I have toddler photos of her tucked in my bed with one of my AOII sweatshirts, surrounded by pandas. I've told her ever since she was a child that if she went to college, I'd pay for her sorority membership. I truly don't know if she'll be attending college, but if she does I'll hold true to my promise no matter which sorority she joins (but oh how I'll want her to be an AOII!)
