The going is easy,
but the way back is scary.
الذهاب سهل، لكن الإياب مُخيف
Gut, geht weiter,
aber der Rückweg ist mühselig.
La ida es buena,
pero la vuelta es complicada.
La ida es buena,
pero la vuelta es complicada.
L'andata è lieta, il ritorno spaventoso.
Seguir em frente é fácil,
 mas voltar é de dar medo.
