Responsibility

Responsibility.

Some are born with it.
Some are not.
And they never take it upon themselves.

We're 6 siblings.
Some live closer, some are far away.
Some have large families to take care of, some have smaller.
Some are right before / after childbirth, asome are not (the males... :-) ).

5 are evolved with caring for our parents, in various degrees.
1 is not.
Well, not quite not at all, but he doesn't take any initiative to do things, if he is not implicitly required.

Will he ever grow up?
