When you take off your coat on a cold day, you risk catching a cold. When you pour vinegar over soda, you destroy the good quality of soda as a cleaning agent. So, we are shown foolish and inappropriate behaviour twice. These two images strongly encourage us not to visit a mournful person while singing happy songs. That kind of music is not suitable for a person who is sad; it causes irritation instead. Be aware, therefore, of inappropriate behaviour!

So, we are shown foolish and inappropriate behaviour twice. These two images are strong encouragement to not visit a mournful person while singing happy songs. That kind of music is not becoming for a person who is sad. It causes irritation instead. Be aware therefore of inappropriate behaviour!
20 Whoever sings songs to a heavy heart is like one who takes off a garment on a cold day, and like vinegar on soda.
