Yes. Shortcake is an actual cake: it's sorta like angel food cake, but denser. Shortbread on the other hand is not bread or bread-like at all, but it is rather a cookie (or, if you're British, a "biscuit", but not the American kind of biscuit, because it's not leavened/puffy). The example given is a good but not the best example, because Girl Scout Cookies are no longer of the quality they once were, but there are some really good shortbread cookies you can buy at the grocery store. They are very rich and buttery, with a soft crunch. Recommended :-)
But i guess there are boarding schools were the kids stay there
