Someone in my family kept trying to get my pin number. They would give tons of reasons, like they were going to the store and had no money, so they'd pull some out and repay; or the more elaborate, I got scored pot but need money for it, but you're too drunk to go, so let me... and so on.
Then one night we were drinking, and he kept drinking a lot, or at least I thought so. He was actually pouring the liquor bottle into a glass and putting it behind the couch. Finally the bottle was gone, and I wasn't drunk as I wanted to be, but was drunk enough to not wanna go anywhere. This person then said he felt the same and would go to the liquor store and get more, but he needed my pin number since he had no money of his own, and would use my card--I also had no cash on myself.
I was way too fucking lazy to want to go do it myself, so I gave him my pin, and he wrote it down. He then left. I eventually found the glass full of liquor behind the couch, and figured he just forgot about it. So I drank it. Yeah I was an alcoholic back then, but still functioning. By time he got back, I was really drunk, and barely had any of the beer he gave me. I ended up blacking out and falling asleep on the couch.
The next day I went and pulled some money out of my account just in case I wanted more liquor again. I pulled 100 without any issues. I didn't bother taking a receipt since I knew how much I had in there. I went home and did my usual nightly drinking.
Toward the end of me spending all of my cash on booze, the internet went down. This person knew I'd check my bank account online. I just shrugged and played video games or watched movies in my free time. But by the third day, I was getting sick of this. I went and checked the phone lines. The cord looked plugged in, but then I looked more closely. It was just SLIGHTLY unplugged, so from a distance it still looks plugged in. I plugged it in, and my internet started working again.
Only NOW I became suspicious and checked my bank account. It had been emptied. My savings and even my credit card was emptied to the point that I was in debt by thousands. Before this I actually had a decent amount of money and my credit cards were always paid off in time.
I went to approach this person, but they were already gone. I don't know how they figured out I figured things out, but they were totally gone. I searched the house, and found a crack pipe made out of a literal fucking pipe. Later on I'd figure out this person had a crack addiction and was in debt to some real rough guys after he tried to deal crack to make money, but just ended up smoking it all.
The red flags were clear as fucking day. I lost count on how many there was. But in the end I was in debt, and having bad alcohol withdrawals for a few days since I was an alcoholic at the time and a daily drinker. I could have went to the pawn shop and got back my debt pretty fast and went back to drinking, but I didn't want to stoop to this level, so I sobered up and toughed it out... only to attempt suicide a few weeks later. I didn't sick the cops on him because he was a family member, and I'm sweet like that.
