thanks donna. he is still active duty, and they are putting him in hazmat classes, and the instructor is going way fast for him, he isn't 'book smart' as they call it. they are craming 3 months worth in 2 weeks. his first test is , today, and i am sure that his 'studing' hasnt helped, he needs things broken down, bit by bit, and its too much for him right now. i offer every night to help him study, i enjoy learning what he does at work, but he doesn't want to , or if he does, he sure has a odd way of saying it.
