Now I ' m not renowned for my emotional side but this really gets to me , for some reason . Likewise , when driving up here yesterday , I saw a man whose car had broken down trying to push it over the kerb and onto the sidewalk out of the road . As he was having difficulty getting it over the kerb , another man rushed across the road , quick as a flash , and lent a hand .

The show of profound altruism was really quite nice , and they could n't help but be touched
