Its all in a name... or a nickname

There are some people whose name just fits them. She just looks like a Danielle or a Sarah. I couldn't tell you what exactly a Danielle or Sarah should look like, but you know when someone looks like their name. It doesn't happen often, but when it does it is so noticeable, it is astounding. These names are always easy to remember because, for some reason or another, the face triggers the mind to remember the name. But there isn't an abundance of people who look like their name, so we need to come up with other ways or either remembering names, or other names. Often what does happen, is that a person is given a nickname based on what they look like.
Now, when someone gives us a nickname like this, we usually are completely unaware that this nickname for us even exists. It is usually used when someone's real name is not know, but for some reason or another, this someone needs to be spoken about. Today I was sitting at lunch with a few friends, and one of them said, "I almost ran into glasses-kid today." Another friend then asked who glasses-kid was. Clearly glasses-kid is a kid with glasses, but since lots of people have glasses, it does not seem that this nickname would be overly useful in figuring out who glasses-kid actually is. But this guy actually looks like glasses-kid. If you saw him or walked past him, you would know that this guy is the guy called glasses-kid. It is quite interesting how you could have never seen this person in your life, only heard stories of him in which he was called glasses-kid, and when you meet him or see him for the first time, you would know exactly who he was. You know him because the nickname glasses-kid is so perfect for him. Our language and the words we use and the names we give people can be so perfectly descriptive.
A few minutes later, still at lunch, a guy from my dorm walked by and one of my friends called him over. She then proceeded to ask if she could call him Frodo. I know that you can picture him right now. And yes this guy has dark hair that sits in these little curls that float like a little fuzzy helmet over his head. Frodo is the perfect name for him because it tells anyone and everyone who has ever seen anything related to The Lord of the Rings movies would be able to pick this guy out of a crowd if you ask to pick Frodo out. Nicknames can be so perfectly fitting to someone, that no confusion could ever be made as to what his or her name was, or at least nickname was.
