Today. I got a new case for My contacts. There was an "L" on the cap made of dots. I was confused by this new design and then contiued to ask my older sister, "I wonder why they have an "L" on the cap made with these dots?" and after we ponderd this question for 2 min. She exclaims "OH! Its Braille! Dummy, you know for the blind people to know which cap is the left one!" After satisfied with this answer I told my little sister about how the world is becoming "Blind Friendly" and about my new case. She then slaps me on the head and says "Blind People Dont Wear Contacts!". MLIA
