I resemble your remark! Married to an engineer, love him dearly but I NEVER ask for help. Yes, I want a big ironing board but it will have to wait until he's not around. I have neither the time nor patience while the man reinvents the wheel. :)
I tell him his talents are better used elsewhere, so go play with his car. It works. I employ others to do things for me. Although I must say I never have car issues.
I must say I am fussier that him on certain things.....
