why people get hurt?

so many people around us, we thought they are like a friend or connected with them but that same feeling they also think about us that not necessary.
sometimes what happens with us we connect so much with them and we start expectations from them and now where we start to get hurt actually in starting 
they fulfil our expectations but after some time, they busy in their life or we can say they go ahead in their life but we stand still their and 
expect same, from there we got start hurt. nowadays the truth is everyone is busy in their life they are with us but on their choice or comfort not like as
we want or need this is a fact every time no one can stand with us when they are with us then we fearless but we don't realize that we become dependent on that 
person and we realize that truth when they are not with us then we realize the value but sometimes when we realize that till then they go ahead in their life
and sometimes we caught them again when caught them again then we got happy and we lose then we got hurt basically we are dependent on another person.

now start thinking differently if we do something for someone and don't expect the same thing from that person you just do for them and don't think that they will 
also, do same then trust me you will not affect that much as normally we do.
now days world truth is everyone selfish in this world but in this selfish world life give you a true person who tell truth in front of you for your batter
life then trust me just hold them like long term investment for long life they really help you in this life whenever you will miss your path then they will 
realize you before your loss that you are on the wrong path that only can do parents but sometimes what happened with us every parent wants that kids must be safe
and secure always they scared when kids want to do something new or different they want kids must be a success in their life but with all safety and security 

sometimes parents give full freedom they never stop their kids to fly because they thought if you will not fall then you never learn the value of life or success
but they always stand behind their kids and kids realize that when they fall and when they see who's helping them to come out their problem but trust me that only
can do parents at the same time you got friend also like that then you are so lucky in this world.
sometimes what happens that we are not living with our parents or friends also live far to us we can connect now only by phone very less we can meet with them.

     everyone busy to handle their life challenges, so we start to think we are alone no one is with us and start depressed because of this.
why we trust blindly to anyone we should not trust anyone like that. trust is a very important part of life as like money actually trust is important more than the money we can earn money again but trust if we loose then can't gain again or if we gain again then always will be in so many doubts.....
