Covert contract. I would not send her the bag of memories. She had her chance to pick what she wants and she did it. You putting these things together for her is 1) telling her she's lazy; 2) feeling superior for your good behavior; 3) feeling like she owes you now; 4) not doing it for yourself since you find these memories very precious; 5) deciding for her what she wants; 6) pursuing to a certain extent.
What the WW wants is to escape our control, to owe us nothing, to move on, to free themselves from the past. These kinds of initiatives are just ways to remind them that we want to have a say in their lives and they're not even good for us. Forget about the bag: if she wants something more, she'll ask you.
