Been trying to find one for a few days now. I don't remember anything except it's two childhood friends reuniting again. They were really close, one moved away, and said they were going to start sending letters to each other, but it never happened. When they reunited one said "We promised we would send letters, but that stopped." And the other replied with " Sorry, I was busy. " With illustrations referencing she had new friends.
I tried looking at the childhood friends tag but still can't find it. Anyone got any ideas?
