trying it but only one option!!!The next weekday after that clue appears, I would suggest not talking to Claire(Mom) in the morning to get a chore. When you talk to Valerie at 1000 there should be a new option to reward her in addition to the you need her to do something for you option. Pick the reward option and you will go to the park with her.
Edit: I mean Veronica. Why the hell do I keep calling her Valerie today?
