You probably know a couple of people in your office who need these flashcards. You can never tell if they're being sincere or sarcastic, and they often leave you feeling you've been bamboozled by their bad mood. After a short conversation near the coffee pot, you don't know whether to weep, laugh, or stick your tongue out in distress. Pick up a pack of these playing cards and worry no more. Like real-life emoticons, simply hold up a card to show that certain someone how they're making you feel and ask them to pick a card that represents their current mental state. Sure, there isn't a figure holding up a middle finger, but of the 40 emotional states represented in the deck, they'll find something that fits the bill.
