Why...

does he become the person I want him to be, the father I know he can be when he's leaving? Why does it take him going away to spend the time, have the fun that he should be having with them all the time. Does he do this on purpose, does he want to make it harder to say good-bye? Or is it just kickin in that he's not doing what he should be doing on a daily basis? I guess I should just count my blessings that he does this at all. This way they have some special time and make some memories with him before he leaves.
