This is going to seem a bit rambling but bear with me, it does relate to something that happened today.
So back when I was at university a friend, I forget which one, mentioned spotting someone who looked like me on a bus. Not so amazing, but they stressed that this person did look exactly like me to the point that they almost went over to say hello. I definitely wasn't on that bus so I decided I must have an evil twin, like The Dark Half. The twin came up in drunken conversations and was occasionally used as an excuse but was otherwise never heard from or spotted again.
Cut to a few years later and I'm living in Chelmsford. There was a shop in the station near my flat that I used to pop into on the way to work everyday for cigarettes. The bloke who worked in the shop came to recognise me and to know what I came in for, but then one day he hands me the wrong brand of cigarettes. He realises his mistake, but explains that there's someone else who has started coming into the shop every day who looks exactly like me but smokes different cigarettes. From that day on he never really confused the two of us again, but would occasionally say things like 'I saw him again the other day - you really do look identical'.
This goes on for a few months, then one day he tells me that the other me is leaving to work in Cambodia for some reason or other (at this point I start to wonder whether my twin is actually the evil one of the two of us as he sounds like quite an interesting chap). He is so convinced that we look alike that he wants us to meet so I can see for myself, so he asks for my phone number to pass onto the other me. This is obviously a bit weird but the bloke is pretty insistent and to be honest I am a little curious so I give him my number.
I don't hear anything for a few days, then I go into the shop and the man says that he gave my number to the other me but the other me said he wasn't going to phone me as he thought it was weird. Again I'm wondering if he's really the evil twin as he seems a lot more sane than I am. Anyway, he left for Cambodia and I never heard anything else about him.
So I'm walking up to the office where I now work near Brighton station and as I'm about to go in the receptionist bloke comes out with a pile of letters in his hands and says 'Are you going to the office?'.
'Yes,' I say, because I am.
'Great, glad I caught you in time. Meant to grab you on your way past yesterday but I was too late. Can you take these for me?'
He hands me the pile of letters. This is not completely unusual. He often brings the post up to the office where I work, so I figure today he can't be bothered and has decided to have me do it instead. I take the letters and head inside.
'What? You're coming in here?' he asks, clearly confused.
'Yes, I work here,' I say, also confused.
He then realises who I am, and that I'm not the person he thought I was who obviously looks identical but works in a different office nearby. I see the receptionist bloke every day, we say hellos and goodbyes, he knows who I am and yet this other bloke who looks like me is obviously so identical that even when looking me in the face to give me the letters he didn't notice the difference.
'You must have a double,' he says.
I knew that, but he appears to be following me.
