What opinions do you have that you consider (shallow && pedantic)?
On accident
I kind of can't take people seriously when they say On accident, I don't know or care if its more or less grammatical, it sounds like a child sputtering in my mind. It should be By accident or accidentally
A whole lot of grammatical and/or punctuation-related things.
A particular bugbear is people using "disinterested" when the word they mean and should (IMO) use is "uninterested".
I appreciate that "disinterested" has come to mean "uninterested" but since it has another, already established meaning, I wish people would use them correctly.
For what it's worth:
Uninterested - "that has no interest for me, I do not have interest in it."
Disinterested - "that may or may not have interest for me, but either way, I do not have an interest in it."
