Scientists and pragmatic people alike spend hours upon hours trying to figure out why one person likes something and another one won't. Marketing businesses spend millions of dollars testing their products to see which will be more appealing to the masses.
The constant search for trying to figure out human nature has been going on as long as we were standing on two legs; it will continue to go on as long as we remain on this planet.
But I think that people over-look the little things so much. It's who we are, what we like and it's the little things that say more than any other thing could probably tell anyone. Just as appreciating the "little things" in life are important, so are the "little things" we tend not to pay attention to when it comes to getting to know someone.
Think about underpants. A person who wears tighty-whity's is probably a lot less likely to hang loose (no pun intended... well... maybe a little bit,) a person who wears fun, crazy, print underwear probably has lots of fun in life.
Neither is right or wrong, but I'm just sayin...'
"They" say you can never really know a person until you live with them. As per their quirks, their habits and if they are a morning person or a night person. That's true to some extent. But how often do we look deeper?
The brand of toothpaste they like, the way they take a shower... is it shampoo or soap first? How often they floss, do they put their dishes in the dishwasher right away or do they wait a little while? What kind of socks do they like?
I think the same goes with friends though, I mean we don't hang out with people we have NOTHING in common with, but despite their similarities, they will also have their own, unique differences. Not only in specific intrests such as: movies, books or music, but WHY they like it.
Seriously if you take a little more time getting to know the people who are already in your life, by asking about the little things, you might be surprised at what you find.
