Hey, yeah, that opening line is a great hook. I don't care about the protagonist, give me more details on this father figure; I wanna see the "how" too. Start a story spotlighting a character as that, there had better be defined moments to illustrate the claim.
Trying to think of a good reply, but I've been staring at this screen so long I've developed optical illusions of comma-shaped smudges. You know what, I'm making that my response.
