Have I inferred correctly that, in cases where a singular noun ends in 's', some people seem to think that putting an apostrophe after the word makes it plural, even if no possession is applied?
For example, "I put all your syllabus' in a drawer."
Or, "All the cactus' are sitting on the windowsill."
In other words a complete misunderstanding of the rule.
I think I find things like this (and the classic "between him and I") more irritating than when people ignore all the rules.
