Perhaps you're too direct and brazen with people? Too assertive?
This is true, so many people are overly sensitive and don't know how to accept/deal with criticism.
Your bluntness put me off at first, but your a nice person underneath! You keep fools at bay!!!!!
It's hard to put it exactly into words, it's just you. But as I said, I like your personality and I am sure that lots of other people do as well.
