Read the following context and choose the best option to answer the question.
Context: Plus it 's much better than continuing to reach for the diapers on the top shelf at the grocery store . I also met a mom at my breastfeeding support group who also uses cloth and gave me some extra covers that her daughter had outgrown . We met a few other couples that night too . It 's sad that I know the hostess 's name and all the children 's names and ages , but most of the other adults are just " so and so 's mom " .
Question: Why would the people in the support group refer to each other as so and so 's mom ?
Options: 
- None of the above choices .
 - It might be that they feel more comfortable referring to each other with their names
 - It might be that they feel more comfortable referring to each other 's names .
 - It might be that they feel more comfortable referring to each other as mom of someone .
