Bittersweet envy

I saw her Pretty black eyes Long thin thighs Skin that perfectly shines, Yeah I envy her She is beautiful and her parents love her That day she cried, she failed the test But her mum said ''but my baby you're still the best'' walked out of her room, saw her mother crying then father sang a song, making her laugh "darling I'm so sorry" On summer nights, she dances by their side, birthday cakes, roadtrips and lilies Yeah I hate her I wonder,how does it feels, to have a happy family?
