You are:
Unwanted (usually),
unloved (mostly),
and overlooked (almost always).
But still you have a purpose that you go about fulfilling no matter what. Until that mower cuts you down, or that toddler fist grabs you tightly, or that romping dog tramples you. You sprout, you grow, you produce a flower, that attracts various visitors, you soak up the sunshine and rain.
Then you reach the end of your time (at least this cycle) and you let go of your showy petals, and send seeds out on the winds to seek their own spot to grow. The rest of you dies back, but your essence remains in the roots, underground, nourished by a few remaining leaves. And you wait, until it is time for you to go through it all once again.
I love this time of year, when the mower isn't going quite yet, the grass is getting high and the dandelions are dancing across my lawn, providing such a beautiful show. They make me happy just to look at them, at least for a little while.
