Background: my partner and I met in college. We were both English majors, and we both developed a really close bond to one of the professors in our department. She was always supportive of our relationship, we spent time with her outside of class (going out to dinner, etc.), she wrote my recommendation letter for graduate school, and I'm planning to acknowledge her in my thesis. She's always been a source of support and inspiration for us, and we both have an almost familial relationship with her--she's less of a past professor and more of an aunt to us at this point.
Issue: Obviously, we would love to invite her--she's like family to us. I'm playing with the seating chart, however, and can't figure out where to put her. I thought it would be fun to put her and her husband with other alumnae who took her courses, but we honestly don't have enough of them to fill a table and wouldn't want to stick them at a table full of 20-somethings they don't know when they're in their 60s. The other option would be to find space at one of our family tables for them; however, they don't know any of our family and I worry that they would have a hard time keeping a conversation going with them. My partner's family is typically very outgoing but not very academically inclined, and my family is typically very academically inclined but also very reserved (to the point of seeming standoffish). Our professor is fairly outgoing, but her husband is very reserved.
Where would you all seat them if you were in this situation? I'm at a loss.
