Men are funny - or maybe just Adam

Adam does not know our home phone number. It has not stuck in his brain (partially due to a complete lack of effort). The home number is the only way of getting hold of me. As he carries a cell phone (or portable phone book), this isn't usually a problem. However, every once in a while his phone dies or he leaves it home. Then, when he needs to talk to me (to ask for a ride home, say), he's in a bit of a lurch. A couple times he has just walked home, but the latest instance cracked me up. 

The phone rang. I answered and was surprised to hear Adam on the other end, since I knew his cell phone was sitting right next to me and that he didn't know our digits. 

"How'd you get this number?"

"Oh, I just called University Info, and got the number for the housing office, called them, and asked for the number for our apartment. No biggie."

I laughed at the rigamarole he had to go through just to speak with his wife and suggested that he just memorize our number. No action has yet been taken.
