We didn't really get to see these guys together a lot, but I have wondered about a few things regarding their relationship. And I'm not just talking about the fact that Sam was old as heck and that it looked creepy for him to be married to Donna. Donna said that Sam took her in after she lost her parents, and it always sounded like they had more of a father-daughter relationship from the way she talked about him. And Donna certainly didn't act the way she did around Ray when she was with Sam! In other words, I don't think they were in love. So based on all of this, I wonder why Sam and Donna got married in the first place? Couldn't they have just lived together without a marriage? Maybe the show did explain, but I just don't remember? If anyone can shed a little light on this or offer their thoughts, let me know.
