Do you like to write with a pen or mechanical pencil?

i hate pens, only use them to sign my name. i also hate pencils you have to sharpen. i use .5mm click pencils. someone asked me why i use them all the time and i told him it was so i could erase errors, but then i started noticing that i never used the eraser, i just scratched mistakes out like i would have to with a pen. i think the real reason i like click pencils is cuz they are so fine and i can write super tiny with them...and maybe cuz they carry the symbol of changing your mind and taking back what you decided on, even if you don't use it that way.
