Expectations!
you can have expectations on anything but not on your beloved ones as it spoils the relationship..
a big expectation if not met will lead your mind to dissatisfaction and this itself is a sure sign of falling relationships.
i should have been aware that everyone has their own way of thinking just like i have my own way of thinking and acting. but if i start expecting the same behavior from others ( i often do that and very unfair ) life becomes hell...
it does not mean that i expect this from everyone but only from a select few.. but that itself is wrong so i learned...
Life without expectations on your loved ones will be more joyful.. i learned it the hard way.. but still trying to implement the learnings.. some qualities are hard to shed :)
