Unless you share your home with children.
When our silverware (decent, stainless steel, not cheap, but not silver) started disappearing, I determined it was because of yogurt. Our kids would open a yogurt cup, grab a spoon, eat the yogurt, and toss the cup...and the spoon.
I've stopped trying to figure out why. My mother says they'll stop being stupid when they live on their own and have to pay for their own spoons. However, her and my mother-in-law both confirm that none of their children were as dumb as ours.
My solution: I bought a 36-pack of cafeteria grade stamped stainless steel spoons & another one for forks (knives didn't seem to be disappearing as fast).
After 10 years, I just had to buy another set.
Strangely, they get excellent grades, and do really well outside of our house. They are admired by all the other parents. My wife and I are the only ones suffering, and I have maintained that I consider that reasonable.
However, In another 8 years, I'll be able to legally throw them all out of the house. I look forward to changing the locks and having nice things again.
