You do not have to talk too much to buttress your points. People know you little when you say little. And the possibility of revealing your secret or someone's secret is 100 percent if you're talking too much- trying to keep the conversation going, and as such giving the impression that you are an interesting person to be with! Do not be obliged to impress people by being who you are not. Don't forget that we are "judged" by what we say!
Most times, it is not our actions that are been judged, but our words! So say little and listen/observe more! Happy weekend folks!
