i used to want to express what you meant to me in idioms that could reflect how deeply i felt about you, like how you put the stars in the sky or how i thought the sun lent you its warmth when i held you.
but when i think it over, the words that mean a lot to me are the simple phrases when my mom tells me to "take care" and when my kid siblings ask to ride my back.
so i hold you close and say "i care for you," because the words mean more to me than anything else i could think of.
