when going outside after dark there are two well known hazards that the average person should mitigate for every time.
bad drivers and zombies.
you KNOW that you are likely to be run over by a stupid SMIDSY driver so you must help them to see you, and also help yourself avoid being inconveniently dead, by wearing something bright.
For Zombies, you need a chainsaw.
If you come off worse in a confrontation with either, without heeding this sound advice, you must accept some of the blame.
Perfectly Put
