To think it's odd this family don't use terms of endearment?

[WhatGoesHere]

So, a family I've known for over 35 years, all lovely people etc but they don't use any form of endearment in every day life. I've spent many days and nights and holidays etc with them, so have seen them at their best, worst and all in between.
There's no darling/hun/sweetheart/dear/dearest etc
It was so jarring once I noticed.

AIBU it think it's a bit odd?

I mean, nothing at all to do with me, doesn't affect me... but find it a little sad to be frank.

We don’t use any of those terms in our family. In fact, everyone in this house would cringe if any one of us did. Perfectly loving and close family. Don’t see the need for stupid generic terms of endearment 🤷🏻‍♀️
