121. There is no problem that sisters cannot: confront, combat, plot against, ignore, make fun of, drown in chocolate sauce, or run over with the car.
122. I can’t imagine being on this journey through life without a sister as cool as you. Thank you for everything. Happy birthday!
123. Here's to the girlie who shows me every day what unconditional love is. To the moon and back!
124. Sibling love today and always. Happy birthday, sister.
125. Wishing you a birthday that's as wonderful as you are, my friend!
126. Sisters may drive you crazy, but they are the ones who know you best and always have your back.
127. You're such a special friend to me, and I hope you know that on your birthday.
128. Want to use your sister's birthday as an excuse to tell her just how much she means to you? These sentimental, heartfelt, and emotional birthday wishes for sisters will help you do just that! Don't forget the tissues...
129. A sister is a little bit of childhood that can never be lost.
130. I will always be your biggest fan and cheerleader. Happy birthday to the absolute best sister in the world.
131. I learned a lot of things by having you as my sister: how to sneak out, how to talk to boys, how to sass our parents, how to put on makeup, and how to cut my own bangs (that one is key). The most important thing you’ve taught me by far is how to love unconditionally. Happy birthday!
132. Sis, for all the times you defended me when we were kids and consoled me as an adult, know that I am truly thankful. I could ask for no better champion in life than you. Happy birthday!
133. To my sister on your birthday: May your special day be every bit as magical and wonderful as you.

135. May your birthday be beautiful and bright like you.
136. I don’t know what I’d do without you in my life. Happy birthday, dear sister.
137. Having a sister like you is like having a third parent. Thank you for helping to take care of me even when nobody asked you to. Happy birthday!
138. Happy birthday, sis! I want you to know that no matter what happens in life, I’m always there for you. That is what big sisters are for! But I truly hope that your life is mostly full of fun, laughter, and good times!
139. A sister is the kind of special friend you search high and low to have, but she's standing alongside you since the very start.
140. I hope your birthday is as special as you are, my friend!
