She texted me to tell me she was finished and going home (after a two hour wait at the Specialist Office) so I phoned her, knowing she was tired, and asked if I could pick her up. Good thing I did, there was a major accident on the bus route she would be taking home and she'd probably be sitting in traffic still! She texted me later to thank me for driving her home. I think I've got this texting thing down pat now!
