Dear Lady on Your Cellphone in the Grocery Store Yesterday,
You really thought you could manage both, didn't you? You probably thought you were doing a perfectly passable job of manoevering your shopping cart and choosing items from the shelf and chatting away to your friend/sister/mother/husband. But let speak for the rest of the customers at No-Frills and state clearly and without reservation: YOU WERE NOT. YOU WERE A FREAKING TRAIN WRECK THAT MOVED ALL OVER THE STORE.
No one could escape you; no matter where we fled, there you were. Produce aisle? You were blocking the seedless green grapes that were on sale. Cereal aisle? You were perpendicular. Freezer department? No one could open a door without getting around you first. I nearly lost my shit altogether when I tried to get around you for the umpteenth time and you veered into the middle of the aisle and then stopped dead. Seriously, I nearly rammed right into you to teach you a lesson; you should count your lucky stars that you have any Achilles tendons left intact.
I kind of feel sorry for the person on the other end of the phone (although, really, that person had a choice to hang up or not, we had to put up with you no matter what.) Your conversation, while entirely audible to all and sundry, was less than scintillating. What the person you were talking to was going to do with the running commentary on your shopping trip is anybody's guess...."They are out of Nutrigrain bars again" will likely not count as one of the major high's of anyone's day.
Please take this in the nicest way possible: "Multitasking: It's not for everyone". Drive the cart, shop for your groceries, talk on the phone, just not all at once. Don't make me sever your Achille's tendons.
