Ever heard of VCR tape?
What a NOVEL idea!!!! Actually, it did occur to me after I posted the question. Kind of silly of me, huh? The only problem with this is that my husband has the TV rigged up some crazy way so that whenever I ask him to tape something for me (of if I want to tape something), he says, "Oh, it's not set up for that." So, if I want it taped, he'll have to do whatever has to be done in order to make that happen. That means it might not happen without a lot of persuasion and reminders.
Thanks to everyone for your suggestions--especially to spend the day with my son. It's probably the right thing to do.
And to the person who said that your parents didn't go to your orientation--I don't believe mine did, either. And I'm guessing that my son would say he doesn't care if I go or not (he doesn't even want any recognition of his graduation from high school--homeschooled all the way through).
