Grammar mistakes make you laugh . . . except when someone points one out in your novel.
We see them everywhere: on signs in storefronts, on menus (especially), and building marquees. We just can’t believe some of the things people accidentally write (for, surely, they aren’t making those gaffes on purpose)!
“The average North American consumes more than 4,000 Africans.” (Hearty appetites?)
“Toilet only for disabled elderly pregnant children.” (See many of those around?)
Does this make you cringe?
