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
I remember that thanks to the Goldie Lookin Chain song Waitrose Rap, which has the line "10 items or less, were you born in a sewer, the correct grammar should be 10 items or fewer"
