say sorry if it was your fault.. and carry a gun just in case.. even than most people are pure talk... you will encounter the random idiot that if you test it, he will kill you... and you never know behind a keybord could be some gansta wanna be just waiting for a reason to use one of his 24 pistol that he collects . just be careful coz there is a lot of unstable individuals with crappy lifes than might think taking a life is like killing a cat
and even if you have all the proof , you will need address, recorded phone calls, recorder conversation and police reports that show he has been threatening you and you could get a restrain order..
