You realize that you have less friends than a couple of years ago, and your family is more important now.
It harder to see your friends now, it´s difficult to coordinate, you all have different Schedules.
crowds are not "funny" any more. Sometimes they make you feel uncomfortable...
You miss school & socialize always with the same people.
You realize that some of your friends were really your friends, but others that were not as special as you thought.
You realize that some people are so selfish, and some of your friends are not good people at all, and those who you lost contact became your best friends now.
You laugh is more intense, but you cry less and with more pain.
If someone brokes your heart, you ask yourself why did he/she did that.
Maybe you go to bed at night wondering why you can´t meet someone interesting enough to know more.
You don´t like any more the pretty one, you like those who can say a phrase without a damn word in the middle, that makes sense and don´t finish always at the same point; Sex.
And those who have boyfriend/girlfriend start to get married, an maybe if you are in a relationship you are not sure if you are ready for that.
Getting drunk and do stupid things is not funny any more. Go out three times in a weekend is just tiring and too expensive in comparison with you low income.
You look at your job, and may be you are far away from what you wanted, or maybe you are looking for a job and it scared you that you will have to start from the bottom.
You try every day to understand yourself, what you like and what don´t. Your opinions get stronger. You realize that you can´t change the world.
You get worried about you future, carrier, job... And to build a life for you...
