Reading between the lines, we often get to see what’s not obvious. There are situations where reading between the lines can be helpful.
First, It's the people who want to protect us. They don't want to hurt our feelings but to be encouraging by withholding their thoughts.
Second, it's when people don't know how we would respond and choose peace and harmony instead of taking risks or facing discomfort.
In both situations, reading between the lines helps us understand the real intention behind the message. The feedback is rarely about the words on the surface but the overall feelings about the change we seek to make.
