Though I can't read binary, I dated this eastern Indian girl for about a year and a half... She would get really upset, and so to completely take her mind off of things, she would have me write things in binary.
I wrote her a three page love letter in binary (ended up being like 3/4 a page because of the ammount of digits per line)
She still has it. I re-colored the text on the first page to make a red, bolded heart.
