The hardest thing about the hobby is having an understanding spouse.

My wife wasn't into it & used to gripe about all the time I spent in the shop. One day she mentioned wanting to understand. So, I had her do a complete rebuild on my reserve engine. I showed her how & she did the work.
We put it together in a couple days & hung it, I did all the final adjustemnts & connected everything, SHE started it.

The look in her eyes when that lil monster came to life under her hand was all I needed to know she finaly got it. She's been supportive ever since. She's even happy to come out & lend a hand anytime I need it, has been a great help in building my car, one day I'd like to find her one of her own.
