Birthday Card Messages for Your Sister

Birthday card messages for your sister

A sister's card is the one place you can be genuinely rude and genuinely soppy in the same three lines. These messages do both, so you can insult her properly and still mean it.

Bring up one thing from childhood she'd rather forget, then finish with something kind. That's the sibling card formula.
