Here are some quotes about supportive friends:

- "I think if I've learned anything about friendship, it's to hang in, stay connected, fight for them, and let them fight for you. Don't walk away, don't be distracted, don't be too busy or tired, don't take them for granted." - **Jeannette Walls**
- "Friends are the family you choose." - **Jess C. Scott**
- "Love is the only force capable of transforming an enemy into a friend." - **Martin Luther King Jr.**
- "A true friend is someone who thinks that you are a good egg even though he knows that you are slightly cracked." - **Bernard Meltzer**
- "A friend is someone who knows all about you and still loves you." - **Elbert Hubbard**
