How come I can't get my mother and teenage son sims to get along?

I swear I'm talking about my Sims 4 characters. Not a real life family problem. lol Anyway, I have this mother and teenage son sims who I want to get along with each other but lately every time they talk, it ends with either anger, awkwardness, boredom, and annoyed. I realize that symbolizes a normal relationship with a parent with their teenage kid but the problem is, every time they talk, their relationship meter goes down and I really want these specific mother and teenage sims to have a friendly relationship and not suddenly despise each other. I also would like it if the teenager would not get a "familial distress" moodlet every time he and his mom or other family members are in the same room together. The only time I've been able to increase their bond is this mod that allows sims to tuck the other sim in while sleeping at any age and not just toddler and child. I think there may be a few others but for the most part when they have conversations with each other, they don't get along.
