Decency is the act of dressing or doing things moderately. That is not too small and not too little. Doing things the proper way.

Let me tell you a story

So I heard this story sometimes ago.
About a young beautiful girl
On that fateful morning, she work up, got dressed in her best attire. She got to the atm stand and queued for almost an hour before an old widowed woman got tothe queue and begged everyone on the line to please let her withdraw as she was sick and needed to buy drugs. Every one on the queue agreed except this beautiful lady. She even got into a fight with one of the ladies and slapped her on this same Matter.
Eventually, she made sure she withdrew her
money first before this old woman.
You know I told ya she was well dressed. Luckily for her, she met a very big guy that day and they got talking.
Few months later, he brought her home to know to know his place and also to introduce her to his family. And #Guess what???!??!!! The old lady she insulted happens to be the maid of the family..

Moral lesson always dress decently, you don't know who you'll meet on your way. We'll talk about the rude attitude another day
