Best friend sister quotes for the friend who became family

A best friend who feels like a sister is someone you chose who became family anyway. These lines are for that friend, and every one of them is written for two grown women. Use one word for word, or change it until it sounds like you. For the sister you were born with, quotes about siblings has lines about sisters by birth.

An example: "Which one of you is the big sister?" the man at the next plot asks. Saskia, 42, sets down the wheelbarrow of compost and points at herself. "Me. By two years and a lot of advice." Wren, 40, laughs so hard she spills half the watering can on her own boots. They aren't related. They met at 21, when they both answered the same ad for a two-bedroom flat with a broken oven. Now they split a garden plot at the edge of town, along with the tomatoes, the key to the shed and most of each other's secrets. Later Wren texts Saskia a line she's been turning over all afternoon: "Nobody gave us the same parents. We grew the rest ourselves."

Why some friends feel like sisters

Some friendships take years to turn into family, and others feel that way within a month. Typeza looks at this through relationship types, the patterns that show up between two personality types.

Friends in Duality often say the other one fills in what they lack, so time together feels restful. Activation friends wake each other up, and the friendship runs on shared plans and a lot of laughing, with some time apart in between. In Identity, two friends are so alike that they finish each other's thoughts, and strangers ask if they're sisters. Wren and Saskia would say they're the first kind. Saskia plans the beds, Wren remembers to water them, and neither of them wants the other's half of the job.
