All I know is that when the guy across the street passed on, his niece had a cam installed in the doorbell spot, it sees all the way across the street, and alarms if anyone approaches the door, she monitors over the .net from her house on other side of town.....she sees Chuck and I get the paper every AM and set out front chatting and reading in the AM.....and she commented about me sticking my tongue out at the cam....so this AM I saw some ads hanging on the door, and picked them up, waved them in front of the cam, and stuck my tongue out......
