one of the advantages of technology is the caller id (or email sent from).
I screen everything.
and if I get an email from some folks who are over the top with their views, I check the email Subject and delete it....(there is a way of blocking people ... if necessary).
life is too short to waste on toxic stuff....you don't need to constantly hear it..
and as for people who you have to talk to but harp on negative stuff
if I can't make them change the topic (nicely)...then
if I'm on the phone...I take the receiver away from my ear and just keep saying uh huh
or I tell them I need to call them back...then don't.
if I'm face to face...I gotta go, see ya...(be it the rest room, an appointment...anywhere)
cut the conversation
I'm bad...I know....but I'm a survivor
