Asshole Tendencies: There's not a single accomplishment -- from trying a new form of exercise to getting your PHd -- that Tammy won't try to squash. Why? Because Tammy feels better when she's making you feel worse.
Where To Spot Her: Teardown Tammys are like cicadas, they're gestating everywhere about to take over the Earth. Right now your Teardown Tammy may be a harmless larva at work, at home, in your friend circle. But once she matures, watch out!
How To Deal: Dealing with Teardown Tammy requires a modicum of inner strength. When she squashes you for getting a promotion, you have to know inside your heart that you are good and deserving and not let TT make you feel worthless, because lord knows she's going to try.
