I think this is a beautiful and special moment in a person's life, graduating high school. Not a lot of people understand how hard it can be and if you do you should be proud. I guess here this person didn't know how many friends they really had so they have become emotional and it is so understandable! I loved the wording you used to show emotion. You paid attention to the small things like the happy tears. :). And this person is very overjoyed. Because they thought no one truly cared and everyone did all along. :). And that is the best feeling in the world! Well done!
