I ran into a local store today to pick up a few things. With an important meeting to attend, I was in a hurry , so I didn’t take a cart (手推车) on my way inside. As I walked between the shelves in the store, I passed by a young couple and their baby. I continued going through the store, picked up a few items I needed and ended up standing behind this couple in the checkout line.
