Well, take my sister's number (6) and divide by 3. Yes I graduated last in my class, and yet still gave the salutatorian speech. Class of '99
We wore Forest Green. Try as I might, I couldn't convince the other person to wear Royal Blue. I didn't get to wear Royal Blue until I graduated from my community college.
Besides giving the speech, I had a very special ceremony with myself and my parents and lotsa candles on stage (as did the other person)
