I do not think I count as a klepto, but I used to shoplift as a kid a lot. It started when I was holiday shopping for my dad and he came around the corner while I had his gift in my hand. I stuck it (a 75¢ fishing lure) into my pocket. When I got home I realized I had never paid for it. So the next time I was at that shop I took a GI Joe or Star Wars figure. And then two and so on and so forth.
There was a bit of a thrill to it, we were also dirt poor (a pack of ramen for dinner for 3 people, no indoor plumbing, no phone), and on more than one occasion my parents “borrowed “ my money to pay bills and never returned it. Partly I felt it a way to get back at my parents.
My theft continued into my 20s. When my second kid was born it became out of necessity. Her mother would leave us for days at a time without formula, without a car, and without the shared atm card. When my 3rd kid was born I mostly stopped out of fear of being caught and losing my family. But when I saw something I felt was unjustly expensive I would still swipe it.
I have only ever stolen from large stores, Walmart, Safeway, etc, with the exception of the local pharmacy where I used to steal comics because the owner was a dick to me about my skate board.
