You have many toys and most of them play music when you press a bottom or play with them. You like them all, and have never been sensitive to any of those tunes.
But there is one specific toy, with two princesses on two horses coming down a slope. There is a “mary go round” on this toy and horses can be fixed on it and go round. When the merry go round starts, a tune starts. I played it for the first time a couple of nights ago for you. You got sad, and started crying really sadly. Then you said “sad horse”, and you said “horsy dance nakoneh”. So, I stopped the music, and told you not to listen to it if it bothers you.
I myself had a similar reaction to a tune on TV at around your age. A close friend of my mom who is a psychiatrist, and said that specific tunes may make some people sad. It is true about me, even now, and seems to be true about you. So, beware. Stop listening to a music if it makes you sad.
You are lovely and adorable.
