Question

An injury is much sooner forgotten than an insult meaning

Answer 1

yes it is true because injury is only on our external body while insult hurts our feelings.

Answer 2

An injury means a scar on body.

If we apply medicine on the body scar, it gets healed. But an insult is a scar on mind and it takes long time to get healed.

Physical injury can be recovered in its natural course, this is the recuperative power of nature.

But only the time can heal the scar on mind, hence it takes time to heal the scar caused due to an insult.
