Answer 1

Answer:

this proverb tells us the importance of thinking properly before we do something. be it talking, or some other activity. For example, when we are angry we may say a lot of things that may be really hurtful for the other. this can make them really sad. And no matter how many times you apologize, the thought that you said something really bad to them will always be there with them.

therefore, this proverb is just an expansion of the old saying that goes,

"think before you speak"
