I read your title as "I failed as a child"

I had to quickly go and check my title! Phew!

I just feel so bad that I ignored her. She deserved better, and I can't get over it. Dunno why I feel this way, I don't know her, is unlikely ever to see her again and it was just a minute of my life. This isn't how we should treat a child, lesson learnt and to remember for me.
