Many years ago I had a boyfriend who made fun of how much I liked a movie, book, etc., as in "I really liked it" or "I really, really liked it" and so on. Now I find myself saying "actually" more than I should.
Words overused by others that drive me nuts - amazing (and "she did amazing"); awesome ("he did awesome"); anything that starts out with "so"; "well wishes" (where did that come from? what happened to sending someone good wishes?). I could go on and on but "actually"...I think I've said enough.
