Fickle in Friendship
People never forget any wrong done to them by others and any good done to them is easily forgotten. However a believer should overlook any wrong done to him and engrave in his heart and mind any good done to him no matter how small.
Unfortunately, nowadays the tables are turned and people are fickle in friendship and loyalty, and are willing to overlook many years of good done to them, yet are unforgiving even for a single mistake.
