I read this in the early 2000s and I think it was published in the 80s. Only some details of this book stick out to me.
It involves a young girl who sister recently passed away. She takes some of her ashes and buries them in the front yard. She keeps talking about Willow Street and wanting to go back there. Her best friend (who I think is named Chloe but I could be really wrong) is starting to become too cool for her and more obsessed with her boyfriend. Her grandmother has a small dog named Porky. There is a scene in which the best friend calls the grandmother racist. On the cover it shows the protagonist confused looking at the best friend who is in kind of a dream like state.

Hello! This is a bit of a complicated one, since I was only a little child when I read this book and I fear its no longer with me. It was a collection of children's stories with beautiful graphics and art to compliment it. I had it sometime in the 2010's but I think it originated in the UK since it might've been a gift from a family member there.

What I remember the most, and what I want to find is this story that was at the end of the book:

A little boy, who (maybe) visits his grandma. He wants to play but his grandma is far too old to play. When He plays alone for awhile in her garden, he meets a Little girl his age, who maybe had a rabbit toy(??) they play for awhile but as the sun set, or maybe after the day is over, the little girl dissapeared, The little boy was sad but then he realizes that this little girl was the younger version of his grandmother all along.

Im not sure about what the other stories in this book was but I remember it had a family of bears as a front cover and its first story was about a little bear being taught by his parent bear.

This book has been a foggy memory, and I really wanted to find that last story, since its art was so dreamy and painted in a way.
