I believe this because:
1. I'm crazy and allowed to believe anything I want.
2. I have written the following resolution, which I believe to be legally binding:
WHEREAS, my full name is Kristen; and
WHEREAS, "Christ" (.:"Krist") can be represented by the letter X, as seen in X-mas; and
WHEREAS, the letter X represents the Roman numeral ten.
NOW, THEREFORE, it is hereby resolved as follows:
RESOLVED, that from the above information, XX is an accurate representation of the name Kristen.
FURTHER RESOLVED, that I shall be allowed to call myself whatever the hell I want to call myself.
