they don’t teach common sense

when you have two diet cokes sitting on your desk (because to hell with giving up soda when you’re this close to that special time of the month), and you’re not sure which one is the one you brought home today, you have several options to discover which one is the pop you want. 

1.  taste both

2.  shake them and see which fizzes the most

i tried both.  i opened bottle one, tasted it, and it seemed flat.  still unconvinced, i took bottle two and shook it.  ‘well that seems fizzy’ i think to myself.  to be sure, let’s taste it.  right after i shook it.  i think we can all guess what happened.
