Yes, we should know that true friendship never end. As a friend who always stay with us.
Friends should always be careful about selection. Because the bad man's nature is always bad. It is foolish to wish for a better life. There is a possibility of danger from him. For this, we should be friends with good people.
Thank you very much dear @artguru for your valuable suggestion.
To be able to select good friends, you have to observe their behaviour patterns carefully. But that doesn't stop us from having friendly manners with everyone.
