Only takes once to destroy trust

‘What you mean she’s gone?’

‘She moved out yesterday. We packed everything into a van; then she left.’

‘Where’d she go?’

‘I’ve no idea.’

‘You expect me to believe that? You’re her best friend.’

‘You can believe what you like, but she said if I didn’t know, I couldn’t say.’

‘What about a forwarding address?’

‘Her mother.’

‘I don’t believe this.’

‘I didn’t think you’d hit her.’

‘I … it was only once. I was drunk. I said I was sorry.’

‘It only takes once to destroy trust. And it can never be fully repaired.’

‘So that’s it?’

‘That’s it.’
