So, I was actually running down the stairs of a building and at the end of the stairs was a small wooden gate (the building is 4-storey and I was at, half of first floor) and I decided to jump over it, but my leg got caught at the gate and I wounded my chest (the wound was 1mm deep and bleeding) but I drove my cycle to my house, holding the wounded part. 
This is what happens if you do something stupid. 
Instructions unclear, I am already stupid
Oh
