Man's viral post proves why you should never judge a book by its cover

Trying to teach your kids right from wrong should be easy, but can come with many pitfalls and uncertainties.

This is easily done when you start to judge people by their appearances, as we all know that a book shouldn't be defined by its cover.

This was evident when construction worker Andy Ross from Vancouver, Washington, encountered a rather judgmental mother in a store.

Andy, who had been at work all day and was covered in the usual dirt you would expect from a job of his kind, attracted the attention of the woman's daughter.

The woman told her daughter to stop staring and as they were leaving the store she was heard to say "that is why you need to stay in school".

Andy took exception to this reaction and the comment and - rather than start an argument in the store - he wrote a long and thoughtful Facebook post about himself and why judging appearances isn't the best policy in life.

In the post, Andy details his educational qualifications which include medical certification, his own company Evergreen State Outdoors, and why he or no one else should be ashamed of tattoos.

He also concluded it with his 'lesson of the day' which were these 8 points:

1 - Don't judge people at first glance.

2 - Do what you love and enjoy and it's never work.

3 - Blue collar jobs are the best jobs. They can pay great and it doesn't always come with a price tag.

4 - Education is important but college doesn't guarantee you anything.

5 - Experience, hard work and dedication allow you to be successful in your career path.

6 - Don't be an a**hole parent who raises their kids to be an a**hole.

7 - When attempting to insult someone's intelligence and education level, don't allow yourself to be out educated by said dirty man.

8 - I need a shower.

Sage words from Andy and his post has subsequently gone viral. Since 22 May it has been shared more than 163,000 times.
