Chemical reasons. Our middle child displays sensitivity to inhaled chemicals present in the typical indoor environment. Fumes from such common classroom poducts as play-doh, marker pens, detergent residue, new carpeting, body care products, hair gel, soaps/perfumes, etc, predictably resulted in mood-disordered behavior. No doubt she could have been prescribed a drug-combo to sedate her into pseudo-functioning in an indoor public school setting, but we preferred to remove the cause while her immune system and brain matured. PS. Could the good christians tone down the gay bashing? -I had a celibate gay friend years ago hang himself because of such hateful comments. WWJD?
