How to reply by sending a message to the boss when you are not at work?

Send a message to the boss and not go to work. The answer is as follows:

1, I appreciate the boss's concern and opportunity, but my personal situation can't adapt to the working environment in that place at present.

I don't know much about the specific situation of that place, so I need more time to know before making a decision.

I found a suitable position in other places, and thank my boss for his concern.
