Intimidation?

So, I've been wondering lately what leads a person to intimidation. We're all intimidated, it seems, by different people at different times. And then there are those who are never intimidated at all. So, what is it that causes a person to feel these feelings ( or the lack of )? That is my question for the evening.
I like to base my reasons off of different experiences that I can think of. I know some people who are intimidated by those who know more than them. This is how I often feel when my friends use really big words around me. This makes me feel like I'm twelve, therefore the intimidation rises. While this isn't so much the case anymore (I've gotten used to hearing words that I couldn't even guess the meaning to --just kidding...sort of...anyways) I can still see how this would be a main cause or factor.
Age can be another cause for such feelings. When someone is older than you, it can feel uncomfortable adressing them on a regualr person to person basis. You can feel inferior. On the other hand, when one is old, they can feel intimidated by the culture of the younger generations.
Thirdly, gender can be a factor. Some women, I'm sure are intimidated around men, and vise versa ( I have no idea how to spell that). Men can feel intimidated around women because of their emotions, and women with men due to their traditional supposedly superior qualities (absolutely no gender prejudice or offense was meant in any of this paragraph).
Finally, I think that a huge reason for intimidation is personality type. For instance, I know an absolutely gorgeous girl who has the most wonderful outgoing personality. I think this can lead to intimidation. However, I don't think that she should change at all, because that's lame of anyone to be intimidated. Wow, reading what I just wrote, I can tell that it's really late at night. Oh well. Anyways...while having others feel intimidated can be really frustrating, I'm realizing that it really doesn't matter in the long run. Whoever we meet, like, and are liked back by can be our friends, and that's all that matters. Those who are considered intimidating by anyone shouldn't try to change themselves at all. Being considered intimidating is better than feeling inadequit and intimidated yourself.
I appologize if this doesn't make any sense. I'm not really coming to a specific conclusion, but I know that intimidation isn't as big of a deal as I thought that it was when I started writing this blog. Everything works out for the best. Love ya'll. Bye.
