Proverbs 25:20 “Like one who takes away a garment on a cold day, or like vinegar poured on soda, is one who sings songs to a heavy heart.” Often what a person displays on the outside is not what their heart is feeling on the inside.  Life on this earth is full of sadness even though most of the time when asked–how are you–the answer is fine or ok at worst.  Almost everyone you meet has issues which are obviously evident or are troubling internally.  Especially when a person is hurting, and it is very evident, show that person empathy and understanding.  Never ignore a hurting heart.
