You asked your W if she knew how to sew buttons? For real?
In turn she told you she would teach A KID how to so THE KID could teach you?
There are thousands of online tutorials that can teach you very basic sewing skills. Most dry cleaners have a tailor on site. Yet you turn to your W to help you with a basic life skill.
Why didn't YOU LEARN how to sew a button and in turn teach your daughter how to?
These are the things you should be working on. Basic life skills and basic problem solving skills.
