First of all, we don't laugh at misfortunate situations, we cry at them. Second of all, whats so misfortunate about the situation? Theres an able man carrying (helping) an incapable person. Further analyzing the situation, the elder guy even looks like a father figure to the carrier. So, it seems to be an ideal picture of our culture where a son is carrying his father. This is my culture Mr. Birader. I am proud of it and when people practise it with faith and honor, I laugh: not at it, but because of it. So my hearts happy and heres more to that. Ha ha! Say what???
