I have said a million times that hearsay is an English word that means anything coming from the mouths of any1 BUT the 1st party. I've also shown I KNOW about the (silly) legal definition which extends it to 2nd parties. Hence my ref's to "English" and here, "real life".
Just cuz I tell you my cube-mate told me he got a bonus at work, doesn't make it so that he actually said this. My "testimony" in court is hearsay in real life.
In a court setting, it is the legal definition which matters.
