The Secret of Me

Three odd boys.
Perhaps, just maybe, they were normal boys, who did normal things, but then again the only boys I've met have threatened to kill me...
Two having a dark black mess of hair, the other a light, short and blond.
Two smiled, one scowled.
Two wore hats, the other bare headed.
I stood my ground, not backing down from the eldest glare, nor giving in to the youngest grin.
Finally, one speaks, the hatless one, "Who are you?" this question far from polite or kind.
And I stay silent, this thing is something I do best, as for silence, it's kept me alive for all these years.
