Read this in a very popular SOL story this morning and felt it was worth exploring. "eyes had gotten wide". Normally I'd have used the simpler "widened", yet 'wider' implies they instead elongate—possibly looking more oriental? I typically use "dilated', as it's simply a more accurate description, yet it's also a fairly uncommon usage.
So, what're the various opinion on expressions like this? Stick to tradition, picking the most appropriate word or just wing it on the fly and not waste time worrying over such things?
