I'm not talking about old people here. I never expected my granddad to acknowledge the fact that he'd just broken wind because I was pretty certain he had no idea he'd just done it. (My grandma, I'm not so sure.)
I'm talking about perfectly healthy young people who break wind and don't mention it because they seem to believe they've reached a level of maturity that somehow transcends the humble guff.
I had to work with this bloke once. For starters he was a vegan, which really got my back up. Then he passed gas without so much as a cocked leg. Nothing. No "pardon bottom." No "whoops." No "sorry -- I'm just a bit nervous." Nothing.
Like he was better than me. Prick.
