my brother saw my phone

I live with my family. then at that one embarrassing time, I was reading a spicy ppata works and fell asleep without close my chrome. when I woke up my brother was using my phone, I IMMEDIATELY woke up and was shocked. I don't know what my brother was thinking when he saw my phone. FORTUNATELY MY BROTHER DIDN'T COMMENT ANYTHING AT ALL AND JUST LEFT MY PHONE BESIDE ME. BUT STILL I WAS VERY ASHAMED OF MY VERY OWN HOBBY. Starting that day i always clean my chrome history and close all apps before going to bed. And check it twice as if all of that never exist in phone.
