- Her: I want to get him some guitar strings, too... maybe you can help with that
- Me: Steel or nylon?
- Her: Um, if I show you the type of guitar could you figure it out?
- Me: ...
- Do you know what gauge he uses?
- Her: Um...
- Me: You don't know what gauge of strings your husband uses?
- Her: No
- Me: Then you're not buying him strings
- that's worse than him not noticing when you get a haircut
