A blanket can be wrapped around one’s head and used as a helmet. It’s particularly appropriate if you wear your blanket helmet during a pillow fight with me, because unbeknownst to you, I’ll have a brick stuffed at the bottom of my pillowcase.
毯子可以包在头上当头盔用。如果你和我枕头大战的时候戴着毯子头盔，那就更合适了，因为在你不知道的情况下，我的枕套下面会塞一块砖头。
