Tilda is frustrated when her Fitbit stops working and questions whether it might be a battery issue. She's annoyed that her physical activity won't be tracked without the device, feeling that if it doesn't register her steps, the effort is pointless. This device has become her latest fixation, consuming her focus during their daily walks.

Previously, Tilda was preoccupied with posting on Instagram, capturing countless photos of nature intricacies like raindrops on leaves. Now, her main concern centers around counting her steps, showing how quickly her obsessions can shift and influence her daily experiences.
