As I've posted here before, I love to sing and play my guitar on weekend mornings with my first cup of coffee. Liesl will sit at my feet and totally relax and fall asleep when I do this.
For Christmas I got as a gift a Harmony Pedal--a little contraption you hook up between your microphone and amp and when you sing it automatically inserts a vocal harmony. I was playing around with it and Liesl was with me, kind of curious about the new sound she was hearing, but mostly relaxed.
Well, my wife (who is a lovely person but not the best singer) comes upstairs and decides to give the new toy a try. She takes the mic and begins to sing, while I am playing the guitar, and we both happen to glance down at Liesl. Liesl is staring at my wife with an expression of "You've got to be kidding me, right?" on her face. We both burst out laughing at her, and Liesl never broke expression--just kept looking at my wife as if to say "you really should just put down the mic and stop, now."
They absolutely have their opinions, and absolutely communicate them to us.
