This is an excellent quote from "introvertquote" on Instagram.
"I'm a strong believer that not everything you do needs an explanation. If you want a tattoo, get one. If you rather stay home that night, it's okay to miss that party. Don't forget that you are living for yourself. You don't owe anyone an explanation for your choices or preferences."
This quote is 100% correct. Why do you need to go round justifying your choices to everyone? What is the point of that?
Some introverted people feel guilty that they are not out and about raging on a Friday night.
The extroverted people think that the introverted people are strange and real party poopers.
But we all know (or we should know by now) that we are being true to ourselves. You need to recharge and you don't need to give anyone the reason why. If they are true friends they will accept you and your decision. If they guilt you into coming out, run away, run away as far as possible from them.
Remember, it is always your decision and no one else's.
