Is it normal for my family to ignore what's obviously incest?
My cousin is the only child of a single mother (my mom's sister). He still lives with her, even though he's 25 and has a job. He's never had a steady girlfriend.
Almost every time someone meets them, they will ask me if he's her boy-toy. They enter ballroom dancing competitions as partners. We call them Simply Red because they're both ginger, but I've overheard some of my mom's friends calling them Simply Bred.
It's obvious they don't have a normal mother/son relationship, but nobody in my family seems willing to admit it. Every time we mention them everyone looks awkwardly at each other, but nobody actually says anything.
Is my family trying to turn a blind eye to it out of shame, or do they not believe it? I hardly ever see them, so what they do doesn't bother me, but I worry that it upsets my mom.
I personally think it's not my problem, but do you think I need to say something to my mom about it?
