Will he show up?

He wanted to find a room, and then a job. I said, no you must have job to pay for room.
...
I finished by saying I will send him a month's rent from home when he has a job.

Wherever I looked for rooms in Bangkok, they required a deposit of 1 or 2 monthly rents. So a room that costs 4000 THB per month requires an outlay of 4000 or 8000 THB, money many don't have. But clever landlords rent the same room out at 200 THB per day, and those who don't have enough money for deposit somehow manage to cough up 200 THB per day, thus paying 6000 THB for same room!

And you tell us that the trip to Khon Kaen would be too expensive!
