The latest thing I bought for my car are 'eyelashes'. Those are some black plastic lashes pasted above the headlights. What I didn't expect is the effect those 'car-eyelashes' would have on the world around me. People smile and hoot, children wave - and the feedback is age-, race- and genderless. Even the guys who beg for money at the traffic lights. It's just black plastic. It made me think that we often underestimate that it takes very, very little to bring a smile to someone's face ;-).
