Wonder why/how I become this contradicting -

I am tired, but I cannot sleep;
I am hungry, but I dun wanna eat;

interestingly,
The work is tough, but I dun wanna quit.

Happy day

To be happy can be a simple and easy thing - a colleague offered to help out so that i can go home early to enjoy a farewell night with my parents; a stranger from my office offered to give me a taxi ride in the rain.
