I have good and weird friends And i'm not taking the metro with it on my head !! Nooooo... Just put it in the queue for a moment... And during the concert, people will say they can't see anything, so i'll have to take it off anyway... And i won't be very dressed up... I thought about it, then felt like "no"... Maybe i'll change my mind again ! But something sure, i will glow in the dark, once again (like in London, with 10 glowing bracelets on each arm, necklaces, earings )
