Good about the electrician.

Good that Jeff did not seem to feel bothered by the computer stuff.

No, reinstalls aren't hard from a technical standpoint, mostly just a lot of tedium and time, as long as you don't fret like I do. I've seen how my anxiety sets me apart from my development peers. Whereas I freak out, seeing hidden dangers at every turn, they are able to be more clinical, which translates to better executive functioning. It sounds like Jeff has that ability, as well.
