A Special Thank You Note to Your Sister

My sister is my best friend. She probably knows how much I admire and appreciate her, because I maul her whenever I see her (and she’s not the affectionate type). She would like me to write her sweet notes on her good days, send inspirational memes on her not-so-good days, and in general intuit her every need. I know this because I read her diary.

You can’t choose your sister, but you can choose to appreciate what you have. Write your sister a thanks note, just for being herself, and surprise her with your heartfelt expression of love. Use these best sister quotes as a starting point for your note or letter.

“She is my sounding board, my confidante, my keeper of secrets – and my best friend.”

I’ve known every love possible, but as the years stretched out, the love I longed for the most is the one I shared with my sister.

  • “I’ve known every love possible, but as the years stretched out, the love I longed for the most is the one I shared with my sister.” — Josephine Angelini
  • “Your sister is your teacher, your defense attorney, your personal press agent, even your shrink. Some days, she’s the reason you wish you were an only child.” – Barbara Alpert
  • “A sister is a little bit of childhood that can never be lost.” — Marion C. Garretty
  • “A sister can be seen as someone who is both ourselves and very much not ourselves – a special kind of double.” — Toni Morrison

Your sister has undoubtedly helped you learn essential lessons in life, defended you from peers, sung your praises and declared your awesomeness to others, and has given you great advice (solicited or not) through the years. No matter how great your relationship, there are days you have likely wished she were never born. And that is perfectly normal, even after the age of five.
