Always frustrated about some things.

Our family is closest to us.
Yet they are the most irritating/irritable creatures to live with.

We expect more.
We thought they'd understand our situation.
We thought they'd see from our point of view.
We thought they'd know we are tired after being at school for the whole day.
We thought they'd care the way we want them to.
We thought they'd be nicer to us.

I thought wrong.

We are harsher to our family because we assume we know what's best for them.
But other than God, I don't know who esle knows best.
