We all know that Old People have a bit of a whiff about them. It’s no criticism of the person, it’s just a fact.
We can all remember an elderly grandparent, or old uncle, or one of those old people that your Gran told you to call ‘Auntie’ but she wasn’t really your Auntie, it turned out she was just your Gran’s friend.
Anyway, the point is this:
That’ll be you one day. You’ll be that person who, to young people, have a old person whiff about you.
