I'm not the firstborn of my family, but from experiences (what I've seen and heard so far), and reading through your work, I can attest to the fact that firstborns have this thing in common — shielding their pain and acting fine. For Jide, who knew what it would have resulted in had his family been muted from hearing his ordeal?
And I must say, Jide's got really great family. See how they all turned up for him including Eniola, the last born.
