Definitely agree Lilypad13...MT's daughter has suffered through her mother's choices.
The graduation was really an 8th grade promotion, but a yes, a big deal in private school settings.
The school made the decision, IMO, to prevent the media from turning a special day for all 8th graders into a media circus. The date of the promotion was so close to the arrest dates, that many, many media groups (CT, NY, and elsewhere, and the Daily Mail) were following MT around. The decision was made to preserve the day as special for other students, not as a punishment for MT or her daughter, MOO.
