Suggesting Recruitment to a PNM

[Missouri Ivy]

I found out recently that my sister in law's youngest sister is going away to a school that no one else in our small town is going to be attending. She's looking forward to spreading her wings, but a little scared about going five hours away, without knowing a soul. I asked if her sister had ever considered sorority recruitment. I mentioned the similarities between her campus and mine (part of the same state system), the fact that the chapters have dorm floors making it a more affordable option than she might think it would be, and that if even if she doesn't receive or accept a bid, it's a great way of putting yourself out there and meeting people. It was a really good discussion between SIL and I, and she said she would definitely mention it to her little sister.
So, I'll probably be seeing both SIL and little sister this weekend. Do you think I should mention recruitment directly to the sister, or should I just let nature take its course? She'd be a great asset to any chapter she joined, but I really don't want to be known as "that crazy sorority lady". Thoughts?
