My 9 year son old has Downs. Can't talk worth a hoot. Knows his letters and numbers, and knows many words by sight, not phonics, which is actually an advantage. Cool. When 2, he could run the computer, save things, call up things, etc.. Thought I lost my wife when he was born and made the list of all to call, etc., but God surprised me! Cool.
Worked with adult Downs, austistics, kids whose parents poured gas on them while they slept and light the match, etc. Have seen kids burn to death. Nasty stuff.
Have patience for those with disabilites, but little to none with people who flake out but are normal. Learning in that one.
