This episode opens with two great things to be in New York: Engaged (Charlotte) and enraged (Carrie). Carrie\'s dead end relationship with Jack Berger has finally come to a close after Burger sneaks out in the middle of the night, leaving a break-up post-it bearing the words \"I\'m Sorry, I can\'t, don\'t hate me\" Therein lies the theme for the episode: getting over a break-up; does there need to be a lesson? Carries attempts to get over Burger\'s insulting split note provide hilarious and realistic scenarioes throughout the episode. For example meeting the friends, fun distractions even trying to make the day related to something completely different memory wise. The three b-stories are not as interesting and slightly more one-dimensional, though each is cute (Charlottes wedding plans), funny (the skinny jeans) and touching (labeling in a relationship). The crowning glory in \"Post-It\" are the scenes involving the pot smoking. Particularly at the end when Carrie dismisses her and Burger\'s break up by declaring that the lesson in it was........\"Wait a minute...I just had it.\"
Definately one of my favorites (and one of the first episodes I ever saw that got me hooked)
