This is the punctuation sign for “because”. It’s simply the sign for “therefore” but upside-down. ISN’T THAT COOL?! I just thought I’d blog this cos it’s pretty useful… for y’know… if you’re in college and you need to write short-notes or whatever :) Take a look at this. It’s pretty useful! :) And follow @brainpicker on Twitter. She tweets absolutely amazing stuff.
