A Mother's Day Poem

I received a little Mother's Day card from Elan, he made it in school. This is the poem his teachers pasted inside:

"M" is for the million things you gave me,
"O" means only that you're growing old,
"T" is for the tears you shed to save me,
"H" is for your heart of purest gold,
"E" is for your eyes, with love-light shining,
"R" means right, and you'll always be.

Ok. I get it. His teachers are foreign.
But still, among all the questions I have, WTF?? reigns supreme.
