As an almost 40 something year old woman who is single, no kids and unattractive and quiet, I often see no use of me for this world. Today, at sainsburys a woman was walking in front of me and on her shirt it said something like 'The person reading this behind me makes the world a better place ' or something to that extent and it made me cry a little. I don't believe it, of course it could have been anyone walking behind her, but still, it was nice.
