hmm what's MIL mean? ok thank you for the input, I really have been worrying about this a ton. She is such a nice lady and I just really enjoy hearing her. I am hoping I see her at graduation and can talk to her for a bit. But if not, I do want to send her an email casually saying if she is in the area if she would like to get coffee, and say that I am just trying to keep in contact with some professors (so she doesn't get weirded out thinking it's only her) I personally think there is nothing wrong with it, but I just keep feeling I am overstepping some sort of boundary...
