A wise person hears one word? meaning?

Can anyone tell me what the meaning of this proverb is? "A wise person hears one word and understands two" I have a few different ideas. I need this asap. THANK YOU!! You can email me also.....Thanks..Susan in PA

My opinion: a wise person hears and understands another individual's spoken words. But he or she also understands the underlying message, concerns, feelings, etc. of the speaker. The wise person can read between the lines.
