Please study the tutorials listed at: "An example is worth a thousand words." I'd be glad to spend some time perusing and attempting to understand an example (the simple the better, of course) for which ToExpression["soks"] /. ruleOne and soks /. ruleOne typed into separate Input cells under identical starting conditions, where 'soks' is a sequence of key strokes, yield differing results when evaluated.
