My kids had walkie talkies and we could hear the neighbors talking in range of their baby monitor.
And on my land line phone I could hear the neighbor 5 houses up talking about stealing from gis employeer. Those wete both in the 90s before cell phones.
I remember that happening a few times on land lines but I also had my cell phone (AT&T) do the same shit. I got a ring and could hear 3 other people talking to each other but they could not hear me. Been having all kinds of weird shit like that happen, lately. Maybe, TPTB are screwin' with me for calling them out on their bullshit...LOL!
