<human>: Can you condense the text into a few key points?

How i got my scar ? Drunk cycling down a banking and into a tree. Today was the first day back home after working in another city for  a couple of months so no-one saw or heard about my scar before. As soon as my stepbrother saw it he wanted to know where i got it from, so naturally i pulled out my phone and showed him a picture of a bloody chin. Now something happened i didn't know about: My Stepbrother apparently has severe blood-phobia and faints within seconds. He drops like he was knock-out cold and faceplants into the floor. Now he will get a scar at the exact same place i have mine. You can't imagine how happy his overly protective mother is.
<bot>: Stepbrother fainted after seeing a picture of my fresh scar, hit his head in the exact same place. Blood-phobia is weird.
