Dani,
Sometimes you just have to give people the benefit of the doubt. Perhaps she truly thought that she was helping you with her information. Her approach could have used more tact. And, you never know ... perhaps there is some truth to what she is saying from her perspective. It is your business, after all, and if the majority of people are not confused by your name ... then all is well.
I try always to remember what Dr. Wayne Dyer said in one of his books, We judge our selves by our intentions and we judge others by their actions. When I feel a sting come in from someone, I try to back it up ... take a second look and instead of feeling hurt by what the person said or did - I try to see what their intention was. If the intention was to share information that might help me, then I work at going in flow to see if what they said has any gem of truth in it that I can apply. If their intent was to hurt, I'll just let it pass through and not dwell on it.
Your repsonse seems to have worked well for you.
I hope that helps.
