I went to the ceremonies, and they were actually very nice. Afterwards, the student can meeting with their families at one of the many stages and use their code to here their name with their family around them and take as many photos, both professionally and family close up and make the pictures and experience the best. Walking on the field gave a new and unique perspective. Coming in the stadium with your college and friends was awesome and being on camera was nice too. I recommend to be professional in these very important moments, and booing is not appropriate and very childish.
