Here's an original thought (I made it up myself – feel free to use it):
Sewing is like a box of chocolates. You never know what you're going to get.
Here's how I arrived at this great profundity:
Bad news: Several months ago, my machine started making strange and ugly noises and the bobbin compartment door kept popping open. I immediately took it to the shop.
Good news: The problem wasn't serious. The noises came from an embarrassing accumulation of lint. I was soundly scolded by the dealer and I promised to do a better job of keeping the machine clean.
Bad news: The bobbin compartment door popped open because of a crack in the machine cover (probably due to being transported carelessly). The replacement cover had to be back ordered and took many weeks.
Good news: The part finally arrived and I arranged to take the machine in while I was out of town so I wouldn't miss it and I could sew when I returned home.
Good news: The dealer offered a cute little Activa 210 as a loaner and I was more than happy to accept. I would love to know exactly how the light got broken at the dealership, but I'll consider any extra charges as the rental fee for the free loaner. But, as they say, it's all good.
