I remember those words on a poster on the wall when I was serving my National Service.
Basically it means “beware of unguarded talk.”
I tend to interpret it as “keep your promises.”
Over the weekend I heard about how an acquaintance has decided to forever terminate his friendship with another person simply because of that other person’s “big mouth.”
“Always saying this and saying that and he’s got nothing to show so far,” said my friend, “As far as I’m concerned, this idiot has zero credibility.”
Indeed, as a matter of fact, that “big mouth” has become somewhat of a joke within our fraternity.
But people suffer from verbal diarrhea all the time and promise all kinds of shit.
It’s bad to break a promise, but isn’t it worse to let a broken promise break you?
