this is what i have gone through in the past months of being in a class... probably ever since i became a pupil, regardless of where or when.
there will always be...
1. the quiet (either plain dumb or very smart)
2. the loudmouth (always dumb and doesn't hold their tongue)
3. the funny (50-50 on this one)
4. the groupie (enough said)
5. the smart-ass-know-it-all (always wanting to be alpha)
frankly i'm fine with the first 4 and definitely detest the fifth.
