This happens all the time. Sometimes it's good gossip and sometimes it's negative. I'm guilty of it but generally I try and keep it to a minimum if it's brought up.
To be honest, I rarely pay attention to any of it unless it's something that's truly concerning. I could give a fuck less about why Sally is mad at Harry.
I definitely didn't expect that my life was going to be private or discreet when I started doing this especially when forums like this exist and there is constant communication between people. I really don't care if it's just petty stuff. The majority of the time I don't care enough and forget anyway.
