I went to buy groceries from the supermarket. As per the process, I was at the baggage counter for keeping my bags and I noticed that the lady at the duty had a cold. There was not much I could do right there, so I asked her whether she had taken any medicine for her cold. While her answer was in the negative, I smiled at her and told her that I hoped she would feel better soon. She gave me a big smile, almost as if she was thanking me for just asking after her health.
