Emotional sister quotes are for the moments when a simple ‘love you’ is not enough: her wedding, her first baby, a goodbye at the airport, or the night you finally say thank you for everything. These original lines are written to be read aloud, tucked into a card, or sent at midnight, and every one is free to use.
Below you will find tear-jerker lines for big milestones, little sister quotes from the older sibling’s point of view, a short list of the best sister quotes we have written, words for sisters going through something hard, and lines for saying thank you. Every quote is original to Betteroo, so there is no risk of a misattributed line.
For the wedding toast, the baby shower card, or the speech you are already nervous about. Emotional sister quotes that hold up when your voice wobbles.
