Sorry seems to be the hardest word

Nothing is truer than the statement above...something which I just found out. Dunno why, but I keep getting into people's way these few days, talking back at my colleagues just becos I was pissed at something else, poking my nose into my sis's affairs and etc etc. Then I would start to feel guilty soon after...and that feeling is certainly quite an unpleasant one. I know I should apologize, but it just doesn't come easy man! While the guilt keeps gnawing at me, the word 'sorry' just keeps getting stuck in my mouth. But I'm glad to say, I did it! And boy, did I feel good after that! I must say, the courage it took for me to apologize, was even greater than any other times when I needed to do something brave, like taking my music exam, or going for roller coaster rides! But I really didn't want my stupid impulsive behaviour to ruin the relationships between me and my colleagues, sister, friends, etc. I would want to be known as a person who is not afraid to admit my wrongdoings and say the important word 'sorry'. I guess I had also wanted to set a good example for my sister too. I know I cannot hope to not commit anymore mistakes in future, but I sure hope I can learn to be more ready to realise I was wrong and to be brave enough to say 'GOMENASAI!!'
