My FOOT were always cold. "If it goes on like this, I CATCH a cold," I told my roommate, Cathy. "I wish I HAVE a pair of woolen socks. But I left them at home."

The words "FOOT", "CATCH", and "HAVE" are used incorrectly in this context. The correct words would be: "My feet were always cold. 'If it goes on like this, I'll catch a cold,' I told my roommate, Cathy. 'I wish I had a pair of woolen socks. But I left them at home.'"
