When I was a kid, only having started learning to read a couple of years or so earlier, there was a popular song called "Patches" by Dickey Lee. The title character is a girl, of whom the singer laments that his parents forbid him to be in love with her because she's from the poor side of town. I remember for quite some time mistaking the name of the title character (and hence of the song as well) as "Hatches". I remember my sister getting a good laugh at me for thinking the song and character were named "Hatches". She acted as if it were crazy to think anyone would be named that. But why not? People ARE given unexpected names from time to time. Anyhow, I don't remember whether it was before or after the time that my sister got such a laugh at my expense in correcting my idea of tha name of "Patches", but I was in a record store and almost bought a record that I thought at first had the title "Hatches" on it. If it was after my sister corrected me, then I guess I thought I'd prove to her that "Hatches" was correct after all. It was the kind of single records of that era, known as 45s. Anyhow my hesitation to buy it started when I noticed the title wasn't exactly "Hatches", but had an "R" in it, making it apparently "Heratches" to the best of my ability to read at the time. It did seem that my sister had likely already told me that the real name was "Patches", as I vaguely remember already having some doubt about the name being "Hatches", a doubt all the more strengthened with doubt that "Heratches" could be the correect name. So I didn't buy the record. Thinking back on it through the years, and never learning that "Heratches" is a real word, I puzzled repeatedly over what could be the name of the song on that record I saw. Eventually as a grownup, I learned that there is a song called "Heartaches", and decided that that is in all likelihood the title that I mistook for "Heratches".
