Oh, I have to tell you about Mr. Tom.
Mr. Tom came into our lives the 2 years ago. My youngest son attends public school in a class for kids with severe/profound mental retardation. The teacher just walked out and disappeared 6 days into school and there was no replacement. The principal was frantic. She called her good friend Tom who agreed to "step in" for a few days until a permanent teacher could be found.
You need to know that Tom is not a teacher,he was a semi-retired businessman. However he took his "job" seriously. At once he began to organize himself, calling on the lunch ladies, bus drivers, parapros, and parents to learn about each of the 4 kids in his class. He introduced color, light, & sound into the classroom.Within 2 days,he was hooked--even the other special ed teachers were begging the principal to keep him!
That year Tom took my son Christian to new heights. He figured out how to "bring him out" when Christian would withdraw. He figured out how to break things into tiny steps so Christian could finally be successful. He discovered my son loved music and used it to encourage & reward him. By the end of that year, he had Christian using a computer for entertainment, feeding himself with a spoon, and going to the bathroom
at his own request! I nominated Tom for Teacher of the Year because of the improvements he made in my son's education--he won!!
The rest of the story gets better--Mr. Tom stepped aside last year for a new, "real" teacher, but he asked to stay on. He has single-mindedly worked with Christian and now my son is 100% bowel trained--at 10yo

Mr. Tom "woke him up" and brought forth his wonderful, lively personality. He knows my son through & through and is quite devoted to him, and all the other kids too. He has determined he will stay until Christian moves on to middle school. He absolutely loves my son and Christian adores Mr. Tom.
Mr. Tom believed that there was more to my son than anyone else ever did(
except me, maybe. 
)

I will always be grateful that a businessman with extra time on his hands wasn't "too busy" to change a diaper, go for a walk, wipe up spills, and read a book to a challenged but lovely child. He has made all the difference in our lives.
