Oh, hey! what a nice shopping list you've got there! ooh, I see you wrote "H2O" when you meant water. how innovative of you! I wonder what you did with that one second you saved. you must have had so much free time with that moment - you're obviously using that time to conduct something super-valuable, because you're spending $4 to buy something you could just get with a reusable thermos and your kitchen sink.
And you must be some kind of super-genius to know that the water you want to buy is chemically pure dihydrogen monoxide; it's obviously not salinated, chlorinated, iodized, or anything, according to what you wrote. how accurate you are to say "H2O"!
And you obviously need a lot of it. I mean, whatever super-scientific place you work for that would require you to write everything with its chemical name sure doesn't sound like the kind of place that would have water fountains... oh, I'm sorry, (H2O)Ca-2Si3O6-2Al2O3-Fe-K's... everywhere you go.
Oh, and it's also wise of you! drinking water sure is a healthy choice. no wonder you wrote an abbreviation. it must be so healthy that you want to cut as many corners as you can! no wonder the rest of your shopping list is canned fruits and freezer-burnt dinners. I should be worried sick... it looks like it would break your pretty little wrist if you had to put in the unimaginable effort it took to write down all five letters of W-A-T-E-R. I wish you the best of luck on your grocery shopping; you already have it so hard.
