In my family, no one puts on airs.
Everyone in my family is just a plain as plain can be when around other folks. As far as anyone can tell, we're no better than them. It's all one big happy mishmash of humanity, it would seem.
We're very regular. That'd be a good word for it. As right as rain, as regular as clockwork. You'd think, Wow, that brother or sister talks with some intelligence. And that's true. Most of them are highly educated, but when you're around them (us), you're stunned at how down to earth everyone is. Big smiles are offered all around. And pats on the back, without any apparent ulterior motive.
There's no airs, no flaunting of anything. To all appearances, and I'm proud to say this, we're just like anyone else, just like you, just like the average guy. No one can ever tell the difference.
