Conan loves to use the "hone" to call his favorite people: Dayd, Dee, Poppy, Dabbie, Kistee and Ya-Ya.* He's getting pretty good at talking when he's pretending, but still tends to get shy when there's really someone on the other end of the line, so it'll be a while yet before he's having real phone conversations. He's got the protocols down though - saying "Hi" and "Bye", pushing the buttons, even pacing while he talks. It's deadly cute. :)
*That's Grandpa Dave, Grandma Anita, Grandpa Dennis, Grandma Debbie, Christy and Olive, for those of you who don't speak Conan.
