I hope everything goes smoothly, and that you are able to relax and enjoy the party! Emotions will probably calm down after all the stressful events are over...somewhat.
The emotional effects of graduation have revealed themselves in a different fashion at our house...I believe my daughter has said, "I love you" to us more times in the past month than she has in the previous 18 years! Which is good, because with the hormonal level of her 14-year-old brother right now, I can use all the love I can get!
