Maybe this was apparent to everyone using Siri, but today I asked it/her "Who is my girlfriend?" it replied what is your girlfriends name? I told it It then set the alias "Girlfriend" to her and now I can say "Siri send a message to my girlfriend saying I love you" which I think is totally awesome. Im late to the Siri party though...
