I'm always logged in. (g'help me)
Once in a while I run into a batch of threads I know I have not looked at, with no New signal. Let's say, three that I'm sure of. I figure it's a passing glitch re the system here or, at least as likely or more, my computer or IP or something. This has always been a short time matter, and rare at that.
So then I look at them.
Yes, they are new to me. I continue to live.
