I don’t own a backpack.
It’s not for lack of trying. I bought a backpack two years ago. My son liked it so much that he took it for himself (and I didn’t have the heart to take it back again). I bought a backpack last year. My daughter took it on a school trip. And forgot it on a train. I bought a backpack yesterday. I turned it this way and that; tried it on. Paid for it and… Wanting to put it in the trunk of my car a while later, I noticed that it was broken. So I took it back to the store… And I still don’t own a backpack for myself.
Maybe I am not supposed to have a backpack.
(PS: my writing app doesn’t like this post because I used the word “backpack” too many times)
