Have it is a very true saying. Is it

Have you ever heard the saying, “Don’t judge a book a by its cover?” I have and it is a very true saying. Is it good to judge a book by its cover? No, you should never judge  a person or thing by its appearance. It is never good to prejudge someone or something before you find out facts about them. You would not want people to underestimate you so you should not do it to anyone else.
Many people feel that you can tell a lot about a person by observing what they wear and what they eat. Choosing what you wear and what you eat, should not allow you to pass judgment on a person. That is extremely shallow to based it off of those factors. What someone wears and eats in no way to portray one character, behavior, or intelligence. You can not know a person by looking at them and observing what they eat. Thinking like that is ridiculous. Instead of looking at what they wear and what they eat, character should be the essence for opinion. Judging a book by the cover can lead to surprises. Also judging a human by dress can lead to surprises as well.
A person wearing dirty clothes and eating out of the garbage may behave better. This is where you can go wrong by judging someone.  A loafer with good manners and behavior would be more pleasant to be around than a rich, snob with no manners and horrible behavior. One cannot have a full outlook on an individual by just viewing their dress and eating habits. Looking at someone’s clothing or what is in their refrigerator does not depict behavior.
You can not know if a person is intelligent by the way they dress or eat. It might seem crazy, but some loafers are educated, smart people. Loafers on the street asking for money, or food may carry a conversation better than someone wearing a business suit and eating at a high end restaurants. Not all people conform to what society feels is appropriate. Some people may choose to wear a simple t-shirt and a pair of sweatpants, just because they do not feel like dressing up. It does not mean they are less smart or have less money. This mean that such petty things do not get to this person. This shows tremendous strength. Intelligence can not be judged by observing one’s clothing and eating habits.  
I can say, we must look a book, a person, or an object from the inside. The originality comes from its inside . So, we should justify the thing from its inner original content what actually it is. You never want to miss an opportunity to meet or get to know someone. Who knows whats waiting on the other side.
