Asshole Tendencies: Whether it's your new dress or your decision to have a baby or your taste in men, Jane has an opinion on everything -- and it's rarely a positive one.
Where To Spot Her: Leaving tsk-tsk comments on all your Facebook status updates.
How To Deal: Remember that Jane's constant judgments are more a reflection of her own issues and often have very little to do with reality. Don't take any of her snide remarks personally. If you're feeling especially bold, you can try to turn some of her contradictory statements against her ("Jane, is that whole wheat bread? I thought you said gluten was poison!"), but it's usually best to just avoid her disapproving stares when you can.
