i think it’s far funnier to believe sweet dee is named that ironically than some “it was unironic before she hit her head and changed her personality” bullshit
i love the idea of her being a little terror at 7 years old (i KNOW those twins were hell to babysit) and earning the nickname out of pure evilness
“what cute kids you have, that little blonde girl is so sweet!” meanwhile dee is setting a squirrel on fire in the backyard because dennis thought it was cute
