People have too many regrets, regretting not telling what they want to say to the people who want to say; Regret that I passed by someone who should have been a bosom friend; Regret losing my friend who walked with me in the storm; Regret not enjoying the beauty of the world; Regret that I have not fulfilled my due responsibilities and obligations to my loved ones. We can only try our best to make up for our regrets.
