From Redditor /u/RamsesThePigeon:
Back when AIM was all the rage, I started exchanging messages with a young woman. She described herself as being petite, attractive, and physically active, and the pictures that she sent seemed to confirm those claims. For a while, we discussed standard (boring) teenage topics... but eventually, our conversations took a turn for the bizarre.
One evening as we were talking, she told me a story about how she and her twin sister had "switched boyfriends" in the middle of the night. They were caught, and neither boy was particularly pleased about the situation, so in order to make it up them, the girls agreed to have a foursome. The tale struck me as being more than a little bit odd, but I could see no reason for someone to lie about it, so I went right on believing.
Things got stranger from there.
As the months progressed, I was treated to a dramatic saga of epic proportions. First, the girl's twin sister was killed in a car crash that also ended her father's life. Not long after, her mother was killed in an accident (which was strongly implied as having been a suicide).
The girl herself - being under eighteen - was sent to live with her uncle, who forced her to work at a [gentlemen's] club in order to pay the rent. (When I asked how she, a sixteen-year-old girl, was allowed to work there, she told me that "the fire marshal said it was okay.")
That was about the time that the alarm bells in my head drowned out my sense of trust. I went back and reappraised everything that she had told me, and I noticed some rather glaring inconsistencies. After coming to terms with the fact that I'd been blatantly lied to for months, I started calling out every potential untruth that I spotted, and I gave the girl an ultimatum: unless she came clean about who she was, I would cut off contact with her entirely.
She protested at first, going through such acts as being angry that I didn't believe her, and depressed because her "only real friend" had stopped trusting her word. Still, I stayed adamant, and eventually, she agreed to let me see her on webcam.
It turned out that she was an impressively overweight girl who bore absolutely no resemblance to the pictures that she had sent me. Her stories - or so she claimed - were all invented to "keep me interested," because (according to her) I wouldn't have kept talking to her if I'd known who she really was.
Truth be told, she was probably right. Still, I made an effort to keep conversing with her after that, and to learn who she really was... but I never felt like I could trust anything that she said, and eventually, we just stopped talking entirely.
