I'd just like to say that Baljeet and Wendy kiss in Christmas Vacation, which takes place AFTER the summer of which the show takes place during. Thus, chronologically, the two haven't kissed in the show's current timeline, so that can't be used as an excuse. Also, during the period between summer vacation and Christmas vacation, the characters could have gotten older by an age (such as Phineas). By that age, they might' have gotten a bit more mature.

Just sayin'.
