I’ve always been fascinated with words. I discovered palindromes long before the internet, but I never thought about composing one until 2016. For a year or so, I could not think of a palindrome that was more than two words long until one day, something “clicked,” and it just became a little easier for me. I do it for fun, which is good because I am definitely no expert!
