¿por que?

 

I'm pretty sure you can make your signature anything you want. It's just normal to have your name. Or something resembling it anyway.

 

i sign a KAJ. which is my first, last and suffix.

 

I just make my first letters of my name readable, the rest just scribble

 

Same L then scribble, same MI, same T then scribble.

 

All three names, but they're mostly just scribbles. It looks like D~~~~ C~~~~ V~~~~t

 

my signature changes every time i sign something

 

mine changes slightly.

i just scribble something.
especially if its for a credit card purchase

 

It is my fathers middle name as well and the name he went by for most of his life because he didn't like his first name. For that reason alone I refuse to use it except when absolutely necessary and have thought several times about legally changing it.

 

My full name, but you can't read it anyway.
