There is a saying which is "Appearance shows the manner" people do describe based on physical look. But I do always says we shouldn't judge book according to its cover. This is where we human being do mistake.

Although, in a normal view of we people, those boys with dreadlocks or any latest hairstyles are directly called thug or lout because those are the people that do always have the hairstyle.

But boys being doing dreadlocks shouldn't be considered as not being responsible, there many boys out there which uses razor blades to have his haircut but he behaves badly.

The main reason is that the rate of lout that is doing dreadlocks is very high, for example, 100 boys have dreadlocks as their hairstyle, by doing survey, 70 of them will be directly not responsible while 30 of them will be responsible.

So directly or indirectly that is why people agreed that all boys with dreadlocks are irresponsible.

So we should not judge book according to its cover we should try to study one another first before jumping into conclusion.
