You don't KNOW me!

How come it means the same thing if someone is "blunt", or they are "to the point"? I just thought of that, why have I never realised it before? This is going to be a shit post so don't hold your breath... It's funny when you write a plural of something that ends in a 'y' without changing it to 'ie', for example: "Ponys", "Babys", "Batterys" etc. Yup. This window is annoying me...
