I don’t like Mondays from the Boomtown Rats.
Mind, when I first heard it my English was not that good so I really only got the Chorus about not liking Mondays (and who does, eh?). Dismissed the “shoot the whole day down” as an idiom for something which I did not know.
Then at some point much later I realized it’s actually a school shooting.
I feel that. My dad sold my childhood home after my mother’s passing and moved out a few years ago. I had not lived there for 25 years or so, but three of my cats were buried in the yard because I lived in rentals during that time. The last walkthrough through the house was of course emotional, but strolling through the yard past the trees where I put the little furballs to rest really hit me.
