A friend who understands your tears is much more valuable than a lot of friends who only know your smile.
Pain refers to physical or mental discomfort that causes you to suffer in some way. If you break your arm then you will experience intense pain at first, but over time this goes away as the bone heals. Pain quotes can be found that deal with both physical and mental forms and you may find these helpful if you are suffering. Emotional pain is what you feel when you have no physical wounds or complaints but you hurt on the inside and the cause is emotional or mental. Sometimes pain is necessary in order for you to heal and recover but some pain is inflicted due to cruelty or indifference. You should always take care not to cause pain to anyone or anything, not even the smallest insect, otherwise this could come back to you in some way and you could be the one to suffer in the future.
