person A: My oldest and my husband have always had a rough relationship. I've got to believe that as she gets older_comma_ it will get better!
person B: I'm sure it will! I didn't get along with my dad until i became an adult.
person A: That's always good to hear. But in the moment -- argh_comma_ my *heart*. How did your mom maneuver the differences between y'all? Did that wear on her?
person B: Yes it did. I believe she just waited it out and tried to neutralize the conversation when we were together. 
person A: But in the meantime -- the unspoken strain is NOT fun. But I'm glad to hear about a happy ending -- thank you for that!
