First I think we have detoured from the topic.
Second I believe we have gals who party and make good wives just like we have homes that have broken due to Keshas by the wives.
To this topic;-When and where were they taken? If its 9th April, I would say its ok we were all celebrating.Where would be of concern due to her security and image and by extension image of the president.
The photos do not suggest alcohol.I can see a glass with a straw suggesting juice and another where she is holding a bottle which could be non alcoholic wine.
All the same I agree perception is everything and this is not what was expected of a 1st daughter.
Love is beautiful and so are those who share it.With Love, Marriage is an amazing event in ones life time, the foundation of joy, happiness and success.
