I think the unspoken part here is the frame of reference used when defining what the norm actually is. Something your family does that you also do can be considered normal in that context, but abnormal in your wider community. Something people in your community do (Mennonites driving horse and buggies comes to mind) might be considered normal in that context, but abnormal within the broader society that community exists in relation with.
So someone could be doing something they consider to be normal that, from a broader or different perspective, would be abnormal. And it’s usually exposure to that outside/broader position that characterizes behaviour you’d consider normal as abnormal - it’s exposure to a different frame of reference for normalcy.

Yay semantics!
