You found a way to feel connected to her. Sure, your bear is with her, but.. they are both not with you!

So you found another meaningful object, her house. I think you satisfied your curiosity and your missing her with respect--you could have driven by when she was there, hoping for a glimpse of her personal life, but you waited until you knew she wasn't at home to drive by and see her house.

Might it also be a way to tell her, when she returns, that you missed her *this* much!
