A day of swinging high and low.

And high and low.

And high and low.

Kinda like a roller coaster ride huh?

Hence the saying, 'life is like a roller coaster ride'.

But im not making much sense here am I?

Im currently thinking.

But as usual my mind cant function properly when I try to think and take apart stuff.

Nope. I still dont understand myself that well.

Ah well.
