Clyde has reconciled himself to the SOUND of a guitar in the house but will not accept the sight of one. I don't understand this.

My husband and I were learning a song tonight that we're going to play at a benefit on Saturday with our band, and Clyde was a happy little camper while he sat on my shoulder as I sang and he helped -- I play drums in our band so I didn't bother to set up the kit to practice one song, I'll just wing it -- but when Daddy walked by with the guitar in hand, Clyde let out his "gonna fly now" squawk and away he went all the way to the top of the entertainment center, squawking all the way. He didn't mind hearing it afterward as long as he couldn't see it, and even after we'd learned the song and Hubby had set the guitar on the couch, when I started into the living room with Clyde aboard, as soon as he saw the guitar he started making his unhappy noises again so I retreated back to the dining room where he can't see it. Clyde sings along happily when I play my flute or even guitar and he loves recorded music and singing, live or recorded, but he does NOT like to see guitars and freaks out every time. I wish I knew why. I wonder what he thinks it is or why he thinks it's a threat. It's not the size or that we're carrying them, I don't think, because he's unconcerned when I pass him with a basket full of laundry or something like that.
