Gratitude

The definition 
of gratitude
includes the phrase 
"a desire to do 
something in return." 
I am overwhelmed 
by this desire.
But what can I 
give you in return?
You asked me 
if I would 
take care of you.
Yes, if taking care 
means to urge us 
both toward 
our best selves. 
I don't know  
if this is gratitude, 
which begins with 
"the quality 
of being thankful,"
or just a hunger 
to share each rare
and vivid day
with you, a quality 
I'm grateful to you for,
but one surpassing
definition.
