This is a short poem by William Blake that I found in our poetry packet. It's on page 79. I paraphrased it in my own words in blue, and then wrote a little explanation below.
The Sick Rose - William Blake
O Rose, thou art sick! A dying rose!
The invisible worm, A sneaky worm
That flies in the night, That travels at night
In the howling storm, In a bad storm
Has found out thy bed Finds its home in the rose,
Of crimson joy; A red rose;
And his dark secret love And the worm's presense in the rose
Does thy life destroy. Has killed it.
As one can assume, the red rose symbolizes love, and the worm represents death and or decay--the rose becomes almost infected by the worm. The worm is also described as "invisible" which may suggest that the rose is not aware of the worm's harm, or better yet, love is unaware of sickness or hardships.
"thy bed" can refer to both the flower bed itself, or even a lover's bed. It's as if sickness and death is sneaky when it enters a lover's bed? I'm not even going to go there...
