Never a princess but queen

I was at the bridal shop for my gown fitting 2 weeks ago. Some of the gowns that I tried were quite princess-like, so the shop assistant innocently made a remark 'wow, you are like a princess'. By right, I should be happy receiving such a compliment. But I wasn't. I actually corrected her that 'no...I am a queen, not a princess!' I wasn't really fierce to her but i sounded firm with my tone. She was a bit stunned. Darling was shocked when he heard her comment too. He wasn't too surprised about my reaction then because he just knew how badly I resist to the word 'princess'. What's the reason? I simply don't wanna be the second princess. So, I wanna be the queen and accordingly darling is the king, upgraded from a prince. More powerful! :p
