Tokio Hotel’s Bill Kaulitz on friends: “…those are the real friends then…They understand it when I haven’t got time to call them back for 2 weeks. We’ve just got so many thing in our heads at the time that we really easily forget such things. For example, I forgot the birthdays of my parents and some of my friends, but this really makes a friend a friend. You know they weren’t angry at me because of that. Since they know the way I am and that I didn’t do that on purpose. I actually would have forgotten my birthday if the fans hadn’t reminded me!”
As wundertwins pointed out… this must mean he forgets Tom’s birthday too.
