The bravest thing is to always be honest. I believe I'm too mortal to be honest 100%. Recently I was invited to a wedding that I was really looking forward to, but on that day I felt so awful with myself that it was enough to make me not go. I told the girl who was getting married that I was ill. I don't know whether or not she believed me but her disappointment was enough to distance us.
Lying, no matter what colour, is wrong.
