Who gets the memories?
There are no grief programs for people who are dealing with the death of a friend. If you’ve lost your child, your parent, your partner, then there are all these support groups you can join to help you through the process.
If it is a friend who’s died, then you have to cling to the small things that you have to remember them by. This girl obviously supported her friend in her artistic endeavors, while the parents ridiculed her. I would not be returning the sketchbook under these circumstances.
