How upset does disappointing people make you feel, in scale of 1-100?'

'Hmm.. 85?'

'Then... is there something that makes you feel even more upset?'

'Maybe... people disappointing me.'

'Eh...?'

'Then I will wonder not only about my own existence, but also the validity of my judgement. If everything I did was for the right cause and people.'
'Afterall I only trust and expect from so few. I'll eventually wonder if I can trust anyone at all. Believe in anything at all.'
