Hola, me llamo Cristina MJ, pero en este mundo paralelo me dicen Calítoe.:.. Incluso en los momentos de bajón intento tomarme las cosas con humor.

Si quieres comentarme algo en privado, rellena el formulario y comprueba que no haya faltas de ortografía. Bienvenidos a mi cajón de sastre en la Red.
Hello, my name is Cristina MJ, but I'm also known as Calítoe.:. in this alternate world. Even when I'm feeling down, I try to make myself laugh about the matter. Some people like me so much that they have joined my fanlisting (thanks, Iva!); I'm delighted, but I prefer to be modest about that. If you want to tell me something in private, fill in the form and don't forget to use the spell checker. Welcome to my hotchpotch in the Internet.
