This one isn't my own...
About a year ago, my younger borther said he likes when we stay at our grandma's place, because her TV is bigger than ours. Nothing wrong with that, but his reason for wanting a bigger TV was that grandma's TV fits the whole picture on it. He didn't realise, despite growing up in a house with TV's of varying sizes, that the picture shrinks to fit on the screen.
