There’s always a danger when you judge a book by its cover that you might not only get things very, very wrong, but that you might also make a total tit out of yourself in the process.

That’s been proven by one mum, who got publicly shamed in a now-viral Facebook post by someone she’d been rude about in a snide comment to her daughter.

Andy Ross – who hails from Washington – was in a shop when he came across said mum, who seemed a little concerned by his dishevelled appearance… pretty understandable, given that he works in construction and had probably been working pretty bloody hard.

Writing on Facebook, he explained that he’s had a ‘very interesting “educational” conversation’ with a woman and her daughter.

He wrote: “As I entered the store before I got home, a little girl kept staring at me. Which is fine. I know that kids are curious when they see someone, especially as dirty as I was.

“They ended up in front of me as I was checking out. Little girl still staring, her mother told her to stop staring. As they finished and headed towards the door, I hear her mom say quietly to the little girl ‘That is why you need to stay in school’.

“I figured this was a great time to educate this mother and her 7/8 year old daughter.”

He continued to recount their conversation, saying: “First, I happen to be a very educated dirty man. I not only have a high school diploma, I also have a college degree and many medical certifications. So assuming that I am uneducated because of my appearance is actually quite ignorant in itself.

“Secondly, if you are telling your daughter to stay in school because I have tattoos up and down my arms, that will actually suppress her creativity and potentially hinder her imagination as she develops.

Again, contradictory to your point ma’am. I am proud of my tattoos and artwork that Forrest Bateman put on my body. It’s a representation of my pride in my country and my service over multiple combat tours as a special operations medic.”

Amazingly, he still wasn’t done, as he went on to admit he’s not only college educated, but also a business owner.

He continued: “Third, if you’re referring that statement to the hat (not featured) I’m wearing because it features an elk, you might not understand it.

I happen to co-own Evergreen State Outdoors and am proud to own an outdoors company and support my rights to hunt and responsibly be a gun owner.

“Finally, I chose to work in a construction industry. I am proud to say that I am apart of building America and I enjoy my job everyday.

I tried working a desk job when I got out of the service and it wasn’t for me. I enjoy working with my hands and being outdoors.

Subsequently, it comes with being dirty some days. I make good money, have benefits, and am able to provide for my family without issue.

So my appearance reflects nothing to do with my level of intelligence or pursuing a higher level of education.

“I left the the two with a simple final statement of ‘have a good day and try not to judge people before you know anything about them. Good luck with her little girl’.”

Andy then concluded with ‘today’s lesson for the day’, which he broke down as:

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 asshole parent who raises their kids to be an asshole.
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.

Woah, she got SCHOOLED.
