My husband was very abusive to me, in all ways. He would verbally insult me, physically attack me, you name it. One day he had "ordered" me to do his laundry. I had to be very careful about the kind of detergent I used, as most brands would make him break out in awful hives. I took his hamper and our All Free and Clear detergent down to the laundrymat. Remembering about his allergies, I bought a few of the little box soaps from the dispenser. I made sure I carefully covered his clothes in box after box of this stuff, and washed and folded his clean clothes. It didn't take long. The next day, at work, he was itching like crazy. When he confronted me, I said simply: "I don't understand it. I used the same stuff I always do!" He never found out exactly what happened. It was worth it, just to see those nasty red bumps, and the look of agonized bewilderment on his face.
