I honestly miss the days before smart phones and cell phones (and I'm only 28). I think their a great tool but far to many people are dependent on them and miss use them. I've almost been hit 8 times while driving this last month and everyone of those people where either talking on their phone or whatever else and it was blatantly them not paying attention.
I'll play the flip side of the card. I miss adults showing kids respect. I've seen many times where children in stores are behaving and yet other adults act like they don't exist and almost trample them or refuse to acknowledge their existence. Probably not helping with kids showing respect.
Decency for your common man. I saw an elderly women whose wheel chair had gotten stick in between the doors at target and people walked by and ignored her for 5min until I got out of the car and went in and helped her. Same thing with a woman who was buying groceries by herself and had to buy softener salt. I walked out and she was struggling with loading the salt while very capable grown men just walked past. Again I stopped and help and she almost was crying that I did that for her.
Actual knowledgeable sales and customer service. I've got an extensive IT background and can't tell you how much wrong information I've overhead some of which where blatant lies.
