I always get emails and things in the mail from the alumni association at my undergrad university. I always just toss/delete because well, I'm not giving them any more money right now! But realistically, I don't have an interest in donating to the university ever - I just don't get it. When I do donate money it's usually some sort of charity and if I ever did donate to something related to my undergrad, it would be to a scholarship fund (like, I would go find a specific one that I knew gave the money to students in need etc). Am I the weird one or would you someday donate to your undergrad?*
*I just realized that maybe I would consider this if I went to a small private school or something, where I felt a more personal connection.
