Two days ago, I had lunch with a former college professor who lamented the lack of interest American students and teachers show in studying grammar. He suggested our language would be irreparably harmed.
Fast forward to today when I am in line for an attraction at Epcot in Disney World, and a man next to me tells his children that this attraction is not "unsimilar" to one they just left.
Not dissimilar, nor unlike.
Perhaps the professor was correct.
