We live in a cruel world where people talk just about anything that comes to their mind without even thinking if it is right or wrong, and those people get a life lesson from this trucker guy they will never forget.
Being bullied or harassed all the time could turn out to be a serious problem for the victim. Yet there are some which do not care so much about that and mind their own business. But what happens when these people eventually simply explode? Their patience has worn out and that is exactly when they have to say something. Namely, this trucker guy was constantly picked up on because he was still driving an old truck. Everybody was saying that he should get a new one.
