Sometimes, or maybe most of times, people don't treat you the way you treat them.
They could treat you worse, way worse; but they can also treat  you better, way much better.
That's how you learn.

Being treated as a shit doesn't give you authority to treat others as shits either.
That doesn't give you the rights to judge.
That doesn't give you justifications to be an asshole.

You can only be happy or be sad or be annoyed as you choose you will be.
Don't let others dictate you what feelings you should feel for the day.
If someone treat you badly and you want to make fuss about it, then please go ahead.
It might make you feel better.
Please do, for yourself.
Just don't do it for someone else.
Don't do it because they deserve a shitty treatment.
Once someone hurts you, they deserve nothing from you.
But you can still choose what to give them.
And that will define you.

That's what will define you.
Not their words.
But you.
