Well I don't ever call "just to talk". My calls are always as short as possible; I'm either calling to tell him something important that he needs to know right away or I'm calling because I'm on the way home and want to know if we need anything from the store. IM is forbidden at my work, and I have a cheap phone package. Srsly, though, my calls are usually under 3 minutes. Is that too much time to ask to have undivided attention?

ETA: Did I mention that I don't get reception in my office so I have to go outside in Florida to talk? Short calls for sure.
