"Mind your own business" is definitely an interesting name. I suppose by the way it grows, as a sort of ground cover, or fence cover, the name is a subtle way of telling your neighbors to "Mind Your Own Business" ... maybe? Also, I've never heard of "Mother-in-law's-cushion", and the plant looks appropriate enough. There's also the "Mother-in-laws-tongue", which I have had one of those in the past (the plant and the mother-in-law). Way too much publicity for the "Mother-in-Law", far too much. My ex-mother-in-law couldn't stand me, and I was not too fond of her, that's why I say, "too much credit." I suppose there are some cool Mother-in-laws out there.
