The Eternal Bonding

I wonder why he scolds me when I disobey her.

I wonder why she cries when I am rude to him.

I wonder what makes them stay together;

Though their only claim defends their love is long gone.

I wonder why he orders food for all of us on her birthday;

Though he never wishes her himself.

I wonder why he passes her calls of wish;

Though they never celebrate their anniversary;

I wonder why she tries to perfect her cuisine;

Though he points out some reconsideration every time;

I wonder why she takes care of him;

Though I see them blaming each other with others;

I wonder what has made them stick together;

Till the expanse of the horizon;

That which has kept them united for all these years;

That which opposes when someone tries to defame the other;

That which makes them care about the other;

If this is not love; what else would you call that bonding?
