Lily, the walking disaster

"What are you staring at?" I asked her while looking directly into her eyes. She smiled, I don't understand her at all. She was angry at me just seconds ago, is her second nature overlapping the first one, or which one is the first… She is confusing. Why is she doing such stuff, her smiles bring me joy, her happiness is my happiness. She is like a character I want to have anywhere close to me, a companion that would not betray me.
