After she began walking and was on the verge of purchasing her items, she had a moment of doubt. Remembering her past habit of accidentally doubling items in her cart, she decided to double-check to ensure no duplicates were present.
Apologies for the confusion earlier. Here's a revised version:
As she immersed herself in the task, eyes glued to the phone screen ready to make the purchase, a sound disrupted her focus. Glancing up, she spotted Auston near the staircase, sorting through items.
Noticing a considerable portion of the pile missing, she couldn't contain her surprise. "You've made quite a dent in this already," she remarked.
Auston, unaware of her presence, was startled when she spoke. "Yeah, trying to finish up as much as possible. Feeling a bit exhausted, but I'll tidy up and call it a night," he replied.
