The Weed

You say I make you better but you make me worse

You're like a weed in a garden

The Weed see's how beautiful the other flowers are and it wants to be like them or simply in their presence

But The Weed makes the entire garden look bad

The Weed is not a good look

The Weed sucks up all water the rose can be using to progress

The Weed came out of nowhere, snatching the sunlight the rose needs to be great (persist)

You're a problem

Therefore you are removed & forgotten

The garden can now continue to advance beautifully
