She is one of those habits of mine

I have been trying hard to know her
And harder to understand
She is one of those mathematics puzzle
Unsolved, with a million dollar reward

One instant she seems to be around
And invisible the other
She is one of those fire-flies
Playing hide-n-seek, and I always loose

She made me feel happy sometimes
And neglected me most of the times
She is one of those loved-by-all person
Will love me back, but just for a while

She likes few things about me
And hates everything other than that
She is one of those critics of mine
Praises once, writes-me-off a hundred times.

She does everything I have said
And may be, does much more than that
But she is one of those habits of mine
Can quit one day, to start again the next.
