I Take a Day Off

To my surprise, I take a day off, (I surprised myself today by taking the day off...) even though I had prepared today's lunch yesterday.
I think maybe I'm so greedy that I hope to rest three days a week.
From the vantage point of the present (does this mean anything?), people like Grandparents, they only rest one day per week. (What point were you trying to make?)
When I saw the weather forecast in the morning , it said it should be sunny today and I was so delighted about that - but I haven't seen the sun at all up to now, and it is almost lunchtime. (when is now?)
The haze hanging over this city, it makes us melancholy...
I would have to go back to work tomorrow, to do what I don't like to doing, to smile to whom falsely at those I secretly dislike inward.
When will it be over? (what? the haze, the life, the smile?)

The grammar is ok, but the meaning/intention is elusive.

pretty good english, just a few suggestions:

I Take a Day Off

To my surprise, I take a day off, even though I had prepared today's lunch yesterday.
I think maybe I'm so greedy that I hope to rest three days a week.
From the vantage point of the present, my grandparent's generation only rested one day per week.
When I saw the weather forecast in the morning , it said it should be sunny today. I was so delighted about that.
But I haven't seen the sun up to now.
The haze hanging over this city, it makes us melancholy...
I would will go back to work tomorrow, to do what I don't like to do, to smile to whom I inwardly dislike inward.  (or you can leave out "will" in this case, and just say "I go back to work tomorrow, ..." )

When will it be over?
