I am very ashamed to say that I have just hurt someone completely unintentionally.  It has made me very sad and also realise that I need to think a bit more carefully about the quick quip, sexy remark and throwaway line. 
I do find people fascinating and when I meet someone I feel is in need of support, then I know that I do reach out to them to see if I can help and that reaching out can, although I had not thought about it before, be misinterpreted. 
So, lesson learned, I hope, for the future.
