Her phone calls seemed to get farther and farther apart. She seemed distant and aloof and I started to wonder what was going on. I considered her to be my closest friend. We roomed together for years in a spacious, sunny apartment. We had been through a lot together and had supported each other through hard times. We also laughed a lot, and had code sentences that only we knew what they meant; private jokes built over years of closeness. I wondered why she wouldn’t get back to me.
