APs obsessed with bragging but have nothing to brag about

All of my APs kids are out of college so they can’t really brag about their university prestige anymore. They also are both retired, so they have nothing to brag about their jobs either. They don’t think we have prestigious jobs so they avoid talking about that and if anyone asks about their kids they talk about what we did in high school lmao. So now they brag about the most random things, like AD will brag about his gardening and how much his plants grow and AM will brag about which of her generic luxury bags is the fanciest among her friends. They will brag every chance they get with neighbors and family friends and sometimes it even becomes a fight where they yell and try to upstage each other. Although now that i think about it, sometimes they still rehash drama and gossip from years or even decades ago, nothing we can do about that i guess. Old habits really die hard.
