Yay! Good for you!
If you're 62 years old, then you don't need a couple of "moms" telling you what to do! If you want those machines and the power bill is paid, then it's really no one's business!!
I don't really have displays...I have one machine in my living room (a coffin top W&W 8) then my dining room is lined with machines...I have a White Number 8 in there, along with 5 treadles. My sewing room has 3 cabinet e-machines, and I have two others in my bedroom. The portables live where ever they land!
