I worry (a lot)
when I think (of other girls)
about how they (shine)
sparkle and radiate beauty
and about how I could be (brighter)
(and) nothing hurts worse than thinking about
not being with (you) my love, my heart
because I know you (deserve the) best,
you are my (sun), moon and stars
Notice the parentheses.
Read the poem all the way through,
read the parentheses next,
then finally just the words outside
the parentheses.
This one was rather difficult to post.
