Maltese in stroller

We saw a lady pushing her Maltese in a baby stroller today. My aunt said hello to her and she told us that she is pushing her dog in a stroller because it is too old and weak. My aunt, who is ever ready to take out her camera to snap a photo, immediately put her camera back into her bag. As we walked away, my aunt told me that she didn't take the photo because she didn't know if the lady would mind. I think the real reason is that she doesn't want to be reminded of the inevitable. She's a coward.
