Dear Extroverted people of this world,
I know that you like to party. I know that you get energy from being around other people and drinking red bull and socialising. That is great. Let it be like that, however, not all people are like that. Not all people like to socialise and just because they don't want to spend time with you it doesn't make them anti-social. They are not anti-social one iota. Being by themselves and doing nothing is doing something to them. It might sound like the worst possible thing for you to do but for them they are reenergising so don't make them feel bad that they don't want to talk to you. It has nothing to do with you and everything to do with them.
Next time these "anti-social" people turn you down. Don't worry about that. They will come and see you in their own good time and the mean time go out and do what you are good at and meet new people and have a blast. Create new memories and be the friend to these quieter people. Dragging them out to a bar in the middle of town is not being friend.
Remember, not all people are like you and not all people energise like you. The quicker you realise that the better we will all be.
