DS16 had his braces taken off recently and he now has to wear retainers. After only 1 week of having the retainers, he's managed to lose them. We told and warned him many times to take good care of the retainers and to make sure he doesn't lose them.
DS16 is making some money by working as an online tutor a few times a week. AIBU to make him pay for his new 120 quid retainers?
