Like EVERYBODY here, he works where he feels most comfortable.
He prolly feels intimidated around strong Black nerds, due to a prior encounter.
If he is as y'all see him, what would you do in a meeting with him?
Give him props, keep it all positive and drop awareness of his achievements?
(I ain't say kiss up to him, just hold back on any critique).
Or ask him where are the other Black people and let him try to answer cogently.
He's young; give him time/space to grow into his Blackness.
