A thing which I perceive in last few days is that most teenagers suffer from this. Trusting a friend like your own brother or sister and then one day complain about "he/she breaks my trust, now I'm never gonna trust anyone again." Now-a-days a new practice has evolved, of crossing fingers while promising anything. People just think they are being so true to themselves and to God by keeping their fingers crossed behind their back and now they have full authority to do whatever they want with the crap of promise they just made. This has proven to be the base for many little teenage heart breaks. For a small period they remember this treachery but forget it soon and repeat the same process again and again, until, well I can't say how long they can hold on to this, as I'm the one who is still iterating in this loop where I believe God has surely forget to introduce a termination condition. Anyway my point still remains the same. Why make friends? Why trust people? and Why have expectations?
Making friends is the most wonderful thing a person can experience, even more than falling in love. Friends are the jerk bags who can make you do all the crazy things at all the crazy times and in all the crazy places still help you to learn hell a-lot about the life. Even more than your family and teachers. They stand by you when you need them and they are also there when you desperately want them to leave. So no matter you are dumped, cheated or betrayed hundreds of times, you will need friends.
Trusting people was never wrong. Trusting them blindly is utter example of your insanity. I have witnessed many examples where trusts are broken just because a little more than the required information has been provided to a third party. Not even the third party, but also to the partner. Come-on obviously giving your hot best friend's contact number to your boy friend will not give pleasant results. Well I'm just kidding, always remember if a person cheats on you, he/she never deserved you at first. You deserve someone much better. But yes, don't ever trust anyone BLINDLY.
Now expectations. O come-on we are human, and its human nature to expect from people we love and had done some favor in past. It will be stupid to ask anyone not to expect, cause I know no matter how hard you try you will never be able to stop this. Yes degree can be elevate or degrade. And if you actually want to know how not to expect then just go back to your childhood and dwell in the moment where your mother said, "Guddu be nice to people, learn to give and never expects."
