question regarding user Inputs

[cibb]

here is the latest code I've done. I need to clean it up some more but just thought I'd post it up. Also fishing for pointers or advice on how it looks so far.

import random
 
good_bye = ['A goodbye isn’t painful unless you’re never going to say hello again.', 'A man never knows how to say goodbye; a woman never knows when to say it.',
            'As contraries are known by contraries, so is the delight of presence best known by the torments of absence.', 'Be well, do good work, and keep in touch.',
            'Being strong sometimes means being able to let go.', 'But fate ordains that dearest friends must part.', 'All those moments will be lost in time, like tears in rain.']
