Getting loud in the supermarket

Jasmine
I was out at the market getting some things for tomorrow's dinner. I was in the produce section and over heard a mom talking (more like lecturing) her daughter. The mom looked like maybe she was in her 40's and the daughter looked around her mid 20's. The mom called the daughter selfish for not giving her grandchildren like the rest of the siblings. The daughter was clearly upset and embarrassed that her mom gradually got louder with the conversation. The mom started listing reasons why it's selfish and why she needs more grandchildren. I felt sad and kinda angry for the daughter. That's a convo for at home or somewhere private, not a grocery store! I hope things get better between them. Do you think it's selfish?
