Self-Centered

I recently discovered my age has proof me to be very "Khirh".
Which i cant help it myself.
There are certain things that i dislike which I normally enjoy during my teen days.
But I still like to party and have some fun however when the clock tick 00:00 i wish to be in bed or at home.
I no longer have the urge to entertain friends at home like i normally do 5 years back.
I prefer sitting back at home watching movies and play games rather then window shopping.
I find relationship is a waste of my time if he cant promised to be with me till death.
I know I can't marry to the person I Love but I can't stop loving him.
( See my lines above...Heehee )
I find some of the latest hiphop,pop,funky song too earsplitting to listen to. ( Have no Idea WHY?? )
I started having mood swing with even friends which I normally dont..
There are still many more to be scribble down here which i do not longer have patients to form as of now.
All this make sense that i become too self-centered, Not thinking about what others may like. ( I cant help it...Its my age you can blame on it )
