I guess people like the idea of random acts of kindness but maybe in today's cynical world, nobody realistically expects it to happen? and so when it does, one is a bit wary/suspicious?
I generally believe most people are, underneath, good. but I also get "off" vibes from some people. I'm a pretty intuitive and perceptive person and my intuition has rarely, if ever, let me down. VP said she got a weird vibe, why would you ignore that and trust someone then potentially it bites you in the backside and you're kicking yourself for not listening to your gut? I think it's nice to believe in "the kindness of strangers" etc but you've also got to temper it with your own gut feeling.
