We drove her home from her sister's funeral about 10 years ago.
Okay, why do you need to tell her this? Were you no longer friends?
We were good friends even though we had a quarrel a while ago.
I think even the best of friends have disagreements, you know? If you can't agree to disagree, you probably shouldn't be friends.
We didn't part ways.
It's good that you're still friends and I hope you keep it that way for a long time. Being friends with other people as we grow up can sometimes be hard to do, so it is good that you're keeping old friends as you may not know if you can have more friends in your life anymore.
