It was definitely my idea, yet when I came out to Dad, even telling him I had a boyfriend and Indigo did not, he asked, "Is this really what you want?"
It infuriates Indigo to no end to have people assume it's his idea. Me too, actually. I like taking credit for my own good ideas.
It caused me to ask our community "Who started it?" a while back ... I was not surprised by the result.
