noise

I put a basic computer speaker at bathroom in my dorm on the first day when I moved in.

I just connected my mp3 player to the speaker when I taken a shower,
then, I can enjoy in the music.

Today , I chatted with 彥男 who is my roommate and asked him about the voice from my room,then, he became serious about that,
he let me known ,when I was listening to the mp3 in the bathroom , he was speaking the "fuck" loudly every time, but I didn't know until now.
