It’s funny how dads suddenly try to be discreet when people come over though. They’ll still fart in front of you but they’ll make sure that the guests don’t hear or smell it. I suppose it’s their idea of keeping things in the family.
You get used to this though. I personally can’t remember when my dad started doing this. I just know he’s been doing it for a long time. It’s just one of those things that you grow up with and never really bother to think about.
