I had an Amazon delivery guy ring my Roku bell that's at the driveway gate about 400' from the front door. I NEVER get anybody pushing that thing. So, at 9 o'clock in the evening two days ago, I get this weird noise on my phone. Not that I was drowsing on the sofa, but maybe not as alert as I could've been. I pick up the phone hazily thinking it was a call. I was speaking to the poor ba$tard at the doorbell. Said he was a newbie and they gave the newbies the crappy assignments. Delivering to strange houses after dark, not for me. Anyway, my only doorbell experience.
