He needs to wear a school uniform every school day, and this uniform has 7 metal buttons secured by retaining rings. As these were metal, they needed to be installed and removed daily for washing. That equaled thousands of button removals/installs over the years. Yeah. Definitely not my favourite thing.
So now he is in the same quandary, and I'm be darned if I (or anyone else at home) needs to do these buttons for him every day.
"Buttons build character!"
However, being a 7 year old, handling the small metal retainers can be a bit challenging/time consuming...
