To all men and women behind the improvement of my son who has autism thank you from the bottom of my heart. I am forever grateful. You know who you are. Last year, also during Halloween’s trick or treat in school my son’ couldn’t utter a single word. And he had no idea what’s going on. Today, not only did he say “trick or treat” out loud and countless “thank yous” whenever a household gave me some treats, he also had so much fun because he was so engaged with other kids, his classmates and his teachers.
