I've mentioned this before and I still feel the same way. Especially because most people have smart phones now and there's no need to ask for help.
Stuck in traffic on Santa Monica Blvd, ahem, with my windows down -- a business man pulled up next to me and said, "Excuse me? How do I get to the 405?"
I gave him directions, he gave me a quick thank you and I silently thanked Los Angeles for having great weather that allows me to have my windows down. In January. And the opportunity for human interaction - even if just for a moment.
