However, Chambers DOES give dove as past tense of dive, and I certainly do hear people use it here (with long O, as in Chambers); in fact I suppose I have to admit that it's the norm. It's just that I'm conditioned to say dived, even though people have looked at me as if I'm the one who's at fault (probably the same ones who use I objectively, as in "my parents doted on my brother snd I". I often think the world's coming to an end. Like, whatever. :)
