I think having a sewing machine is liking having a pickup truck. It is "odd" enough that it gets on everyone's radar.
And... they remember you!
If you own a truck, you can be sure to get a call when it's time to move somebody - as if it is so fun that you want to take your truck out and run it around the city with a bunch of junk in the back.
Sewing machine = same thing. They think you must have so much fun hemming pants or fixing drapes!
After all, any time spent in your truck or at your machine must be enjoyable for you, right, or you wouldn't own it?
