What to do if you see someone with a knife and they throw the knife to you?

* In many cases this can mean that the person wants a knife fight so they throw you a knife (DON'T PICK IT UP) because once you do then you are accepting a knife fight which can only lead to tragedy. No matter what names you are called don't let it get to you (only fools and spineless people fight with weapons) and back-off slowly (don't turn your back on them.) * Dodge it and run away and call the police.
