(of course it was around 5.30 in da evenin.. but dats beside da point) well da next thin i knw i hear screachin breaks and bam! he hits my bumper and didnt have enough momentem to fly over my car so he was not wounded .. although his fron tyre was not a perfect circle anymore.... my bumper got bent and i got rid of it.. actually it looks better now... oh and da fog light went along with it.. didnt like dem anyway...
