This I know.

It felt kinda funny, in a good way, when my son Johnny phoned me to ask what to do because his furnace was not working. I have my Fireman's Papers for work, as I am a head caretaker at a school and have to do maintenance as well as cleaning. It was a steep learning curve, as I have never been what you'd call 'handy' by any stretch. So as I asked him questions about the 'symptoms' of his furnace disorder, I realized that it had to be his fan belt.Good. Something easy.
