When I was a kid I had a klepto streak for a while. It started out when I was about 9ish with me and my friends creating a thievery group called 'Blades of Steal'. It was named after an arcade video game that was inside a store close to our headquarters, which was inside the unused upper floor of some personal storage place. Someone had previously bashed in a window on the second story of the place, conveniently near a fence that allowed us to climb right up.
From there we stole various crap from lots of nearby stores and brought back our good there to split up or enjoy -- there was lots of candy and such, but also lots of nonsense and worthless stuff, like sardines and random whatnot.
Eventually there was a sting operation (lol) and one of us was caught, cops were called and one store we frequented had video on all of us, or so they claimed. I denied everything and they were unable to produce a video of me, and I was able to point out that it was clearly not me on the tape (it was another of our group, cannot recall his name at all). So, I got away, some of them got boned, and that was that for that.
That didn't end the thievery though.
There was this guy who ran a sports card shop out of the backroom of his home, and we'd go there, steal his stuff, and then sell it back to him. Over and over. After a while he stopped buying, he said he could only do trades, as he wasn't making any money. I do feel bad about this, very much so.
One time we stole several bikes after finishing a swim at a high school swimming pool. We ditched them before we got home, like 10 minutes later (no way to explain that to our parents). Some kids must have been pretty bummed over that.
I did a lot of stealing by myself, as I really ceased to have much in the way of friends after that period, leading up to middle school. In 5th grade I stole someone's cool, sporty walkman. I almost got caught, and had to dump it. Pretty sure everyone knew it was me, though I denied all.
During 7th grade I skipped like 80 days of school, and during that time, nearly every day for a couple of months, I'd hit up a local drug store chain and steal cigars. I'd then go smoke then down by the riverside (didn't inhale, dunno what that was about -- they were flavored). I quit doing that entirely when I went to that drug store with my mom one weekend, and some secret service looking guy with an earpiece followed me around the store, I'd look behind me and he'd be half-hidden behind the corner of an aisle, looking menacing. He followed me around the store, and I was scared shitless.
Another time I stole a can of pop, shoved down 'tween my thighs, and walked out of a small grocery store. I made the mistake of sitting directly out behind the store to drink it, and some old lady spotted me pulling it out my pants, and ratted me out. They brought me into the store and said they can call the cops or I can promise never to come into the store again. I swore! Shortly after that I was in there with my mom and nobody batted an eye. Thankfully.
With a boyfriend I had at 13 I used to go steal lots of stuff, mostly cigarettes and condoms, go smoke and fuck around. Until his mom caught him stealing her smokes and he was shipped away (to Abu Dhabi, for all I know).
There were lots of little things, putting something in my pocket and walking out just for fun, not because I wanted it. I'd throw things away after sometimes. So pointless.
After that my klepto petered out mostly. I stole money for drugs, cigarettes, stuff to sell, etc., all through my teens. None too proud of that. I really cannot imagine doing anything like that nowadays, as I've developed decently upright morals. I was such a screwy kid.
