Use the "good" ones all the time. When I was first married, way back in 1967 and DH's dear Portuguese Mom heard me say something about putting the good china away for "Good Use" she asked me who I was saving it for.....my husband's NEXT wife?
After a good long thought, I brought it out and taught the kids how to eat correctly. Not to say we never used paper plates sometimes, but they do know how to eat correctly. And they didn't break many pieces of the set, not as many as I did myself!
