Continuity mistake: During breakfast, when Charlotte is telling about her boyfriend falling asleep and asks her friends to please help her, Carrie's arms position is inconsistent between the side and front shots: Up/down, arms crossed with left hand over right arm/ left hand vanished with right arm bare. (00:13:13 - 00:13:59)
Continuity mistake: When Miranda is making her bed she is holding the pillow cover with one or two hands depending on the shot.
Continuity mistake: When Carrie is ordering her breakfast Charlotte is looking at her, her right hand on her head. Her fingers are extended or not depending on the angle.
Continuity mistake: After the cute smoker-guy scene, Carrie is on Miranda's bed and her hands swap between crossed or not between shots.
Answer: I'm a long-time fan of the show, having re-watched it many times, and I definitely remember slightly different dialogue at the end of that episode than what's on my DVD. I'm afraid I have no idea why this change might have been made or any other info, but you're not insane.
