Observations

This is some theory I've came up with over the years.

Since I started Poly, taking the train everyday and such. I've theorized a person's character by observing how one subconsciously behaves on the train.

Nope, no thesis. This isn't going to earn me a nobel prize either.
Whether or not you share my sentiments is totally up to you.

Notice when a person boards the train. Does he head toward the centre, or move toward the side?
Centre: Extrovert. Outgoing person who likes mixing in the crowd.
Side: Self conscious. Treasures alone time.

How about where he chooses to seat? In the centre or at the extreme ends?
The theory is similar to that above.

Now let's look at which side he chooses to seat on.
Platform side facing out, or other side facing the platform.
Platform side: Comfortable with current situation but often dream about life outside it.
Other side: Ambitious and exciting, but more often than not prefer the normality that eludes them.

Lastly, which side he chooses to stand on.
Platform side looking out: Down-to-earth person with big dreams.
Platform side looking toward platform: Average with not much ambition.
Other side looking out: Creative.
Other side looking toward platform: Just looking at girls.

Believe it or not, your call!
