iMessages

I was getting ready to head home after the tournament and I stopped at Tim Hortons to message Barb to tell her I was leaving and should be home in 3 hours.  I hooked into the Tim Hortons wifi and sent her an iMessage not realizing that we don't use iMessage now that we have Android phones and use Facebook Messenger.  Fortunately, Barb keeps her old iPod around because she has all her contact information on it and not on her Android.  She heard her iPod beep and so she got my iMessage.  She didn't tell me that she doesn't use iMessage anymore until I got home.
