It's been awhile since I've played it but is it possible you needed to go into the living room and see if there's a quest there? Like... a button to activate it? Or maybe you needed to talk with the sister?
Edit: Ah. Examine the area. Go to the main road in the forest and go right. Keep moving until you see some trees that are down and then go left from there.
I haven't found anything anywhere I've stuck here long enough ...
