Some people are just born with tragedy in their blood.

But seriously, for god's sake, have fun with these kids! Be spontaneous in the classroom. It is sometimes the hardest but most important thing a teacher can do.
Sing to them. Dance around like a monkey. This is the highest paying clown job on the planet! Enjoy it.
Make at least one period a day enjoyable for your students. These kids are stressed and tired. It kills me to see them sometimes. I have one student who has developed tremors from stress. His hands shake all day. It breaks my heart to see this sweet, intelligent kid shaking and shaking and shaking. AND I am a guy, meaning I have the emotional spectrum of a rock, so if my heart is hurting something is seriously wrong.
For example, last week, for a warm-up with every class, I sang the SpongeBob Theme song. I just had them repeat the chorus, and I sang the rest of the song. I even did the little whistle flute at the end for good measure. Then I made each row into a team, and the team that sang the chorus the best got stamps for their stamp chart.
