I was walking along the beachfront to the bus stop this morning, and I got stopped twice by the police. Apparently they were looking for someone who matched my description, and who was wearing the same clothes as me. The second lot I had to show ID to to prove that I was actually me. I never found out what my doppelgänger was meant to have done; the only information I got was when the first lot of police asked if I'd been at the hospital this morning.
I actually have a doppleganger in my home city.
She's got me into a little bit of trouble, a few times in fact. Plus I saw her, walking down the street about 10 years ago, so I know she exists.
One time, I had a client kind of pissed off with me because "I" (the doppleganger) ignored her in a gym when she said hello. She took a lot of convincing to tell her that this 'twin' of mine exists.
I also had an ex's parents swear that I walked straight past them in a cafe and ignore them, when in fact I was 70 kilometres away at work.
Only a few weeks ago, an old colleague of mine followed 'me' up the street and wondered why I wasn't answering my name when she called out to me, and why I was visiting town without telling her.
Scary.
