''Sirius Orr.. Orr.. Or'' Sirius chuckled as his four year old baby brother tried to stutter the name out.
''Regulus Arcturus Black, see? I have no problem saying yours, you're not a good brother'' Sirius mock-teased him.
At this a tear rolled down Regulus' cheek and bottom lip stuck out in a pout. He looked down, ''Sorry''
''I was joking, you can call me Ori only'' Sirius laughed at the kiddish statement he made to make his brother smile.
Regulus looked up and smiled, ''Call me Arc then, special nicknames Ori?''
This memory danced around Sirius' eyes, the day his brother died. He was having dinner with James and a very pregnant Lily Potter.
He heard someone knock, they went outside and saw Kreacher, his mother's house elf.
''What do you want?'' Sirius barked.
''Master Black asked Kreacher to deliever this to you, my poor master'' Kreacher sniffed and disappeared with loud pop.
Sirius opened the letter which read -
Dear Ori,
Remember the one time you said I was not a good brother, well you were extremely right. I am sorry I couldn't be a good brother or even a good person. You got sorted into Gryffindor and we grew apart. I turned into Slytherin and got myself involved with death eaters, and turned to wrong path. But there was no one to tell me Ori, you did the right thing by running away, You could out run the vicious cycle, I got stuck in it. I must be dead by now - but I've completed a task, a task which will probably do some good.
You were a great brother Ori, you always were. I hope in next life, we get to know each other better in better circumstances.
Love Arc.
That was the only day, Sirius regretted running away from Blacks, his sorting in Gryffindor and his friendship with James. Because of all this he ignored his younger brother. Maybe he was right - Maybe Regulus got lost, because Sirius was not there to look out for him.
