CHEAP AND FUN! AND IT WORKS! How many times have you thought to ask someone to turn the volume of the music down on public transports?
And how many times have you thought you should start talking to that girl using the volume of her music as an excuse?
This book, with its double cover, will help with that!
Just show "Can you turn your music up please? I can't hear it" or "Can you turn your music down please? I can't sleep" to your travel mate and break the ice! Guaranteed, you will have a smile back and it will be up to you then... Or maybe just use the book to ask nicely to turn the volume down, for real.
(the inner of the book is a handy notepad for your everyday life)
