Letra de Hello and goodbye

today you're their best friend but believe me tomorrow they don't even know your name friendship is a word that has lost its meaning and making friends a funny game tell me why, tell me why it's always been the same tell me why, tell me why hello and goodbye they came without warning they won't leave when you want it you wish you could beam 'em away but when you really need them they will never appear and if you ask them they will never stay tell me why, tell me why it's always been the same tell me why, tell me why hello and goodbye hello and goodbye it's always been the same it's always been the same I can see by your eyes you thought they'll never go but tell me please where are they now remember me boy 'cause I told you so but believe me you'll get through somehow
