Hi Mona! You said H doesn't understand home maintenance? Yet your Mother is having him come work on a breaker? Electricity is dangerous! Seriously. I've known 2 people in my lifetime who were killed at home working on electrical.
I just want to caution you, that if the job looks too complicated, it probably is - and you guys should call an electrician for this. I'm worried.
On the other hand, dress nicely. Show off! It'll make you feel great, and it'll make him....well, who knows? But I doubt he'll be unaffected!
