When you have a relative who goes above and beyond the call of friendship, duty and love in order to ensure your health and safety, the only thing you can do is show gratitude. Gratitude is never mandatory, except in these circumstances.
It is never compelled, except when the ether says it is. It is never a prerequisite to hope, except when Satan delivers you to death’s door, and her faith compels you to live. It is never a given, unless you also are grateful for God’s kingdom. It will never be curtailed, until eternity comes home.
