The human begins to expect too much too fast.
A man may suffer 100 reverses in 100 days, but the moment he comes out positive on the 101st day, he thinks he can break any barrier.. or even cross an ocean maybe!
A man, who is barely into a nice little friendship with a girl for about 6 months... thinks she should call him his best friend just because she tells him everything she does and tells him everything quite frankly.
But then, he never knows if what he was getting to hear everyday from her was because she really considered him her 'best' friend or just because there was nobody else around whom she felt she could converse with.
May be, in her bucket of friends you probably figure in the bottom part, where the water generally is cold.
Some relations are cold where you don't talk or interact, some warmer, where you greet when you meet, but forget them when you don't.
These are relations which are easier to maintain and where you don't suffer heartburn when things don't go the way you want them to.
But, there are relations, sometimes not the 'bloodlined' ones, where you want things to happen in a certain fashion.. but then you forget that a bloodline is a bloodline... no matter what.
The result : You fall against your nose and the other person does not understand nor realize.
You just have to get up, smile, brush off the dirt and move.
