Jaba,
Agreed on all. My dad used to say that all the time, "It's just common courtesy...". Rest his soul, the older I get the smarter I realize he was! I send mine 1st Class as well, didn't dawn on me to check the tracking number...that's a novel idea... Which leads me to another of my Dad's sayings, "You have to be smarter than what you're working with...". Lol. He loved to tease with that saying...I sure miss him....
