Scariest experience of my life!!!!

The most insanely scary thing happened to me yesterday...it was around 7:00pm local time when my aunt walks into my room and tells me she has this travel card thing thats valid for the whole day....so i decide to go take a bus to piccadilly circus...i get onto the bus round about 7:20 and reach there around 8:00....i walk around for a round about an hour or so and then find my way into this alley way type thing...this guy comes up to me and asks me if i could help him and his friends to push their broken down car to a curb....so i agree...when we get to the car, the other two guys, who were black i might add, ask me for money....i thought they wanted some change....so i dig into my pocket and pull out a couple of pounds....then they ask for my wallet....when i ask them why, all three of them pull out butterfly knives!!!!! at this point my hearts in my throat and im praying to god they dont kill me!!!i take out my wallet, where i had like 240 pounds and 50 euros....they take it all, get into the car, and drive off!!!!THAT WAS ALL MY SAVINGS!!!!!!!!!AAAAAAAAAAAAAAaaaaaaaaaaaaaaaaaaa.....can u believe it...so anyway i run to the nearest bus station, get into a bus and make my way home....
guys ive never been so afraid in my LIFE....you know you think about what itl be like if something like this ever happend to you, and you think "ill kick theyr arse before i give up my money" but man, when it ACTUALLY happens, all macho-ism is forgotten!!!!...
anyway thank god im still alive...
