Hello and Welcome, parents and whomever else i think to mention.
Isn't it wonderful to be here for the graduation of the class of current year and school. Mention length and difficulty of time spent in school. Inside joke about a teacher that makes some students laugh. But seriously, mention pride you have in all your class mates. mention specific friends while lying about how you were friends with everyone. Corny joke, Pause for mild and forced laughter. Platitude. Platitude. Platitude. Overly long boring story. Obscure or overused quote. go specific school. Calmly sit down no longer having to worry about how much you were sweating.
