If u read bl what age did u start at

I was on a bus and I saw a girl that looked about 11 just reading Jinx. She had a full on poker face and was just casually staring at jaekyung just ramming his thing into kim dan.I MEAN EXCUSE ME!? I COULD ONLY DO THAT SHIT AFTER 3 YEARS OF READING BL. HOW TF DID SHE DO THAT. THEN SHE TURNED HER HEAD AND WAS LIKE “ U read bl too?” WTF I MEAN I DID START READING BL AT ALMOST THE SAME AGE BUT HOW DOES SHE HAVE THE COURAGE TO SAY THAT TO A LITERAL STRANGER? I am flabbergasted ╥﹏╥
