The last line seems a little awkward to me.
But maybe I'm just weird that way.

But I do like the poem, it's very simple and to the point. Good job!

I like the last line because although it's simple, it carries a lot of meaning.

I don't like the first/second lines; I think the first line repeated. It's particularly an eyesore in a poem as short as this, so I suggest fixing it.
