Yes, you will have no problem returning to Bangkok on another visa exempt entry. If you have done this 5 or 6 times in a row than maybe immigrations may become suspects. But not in your case.
Update: Even three times you still will not have a problem. Immigrations is looking for those who are working here and using the visa exempt status to stay in Thailand.
Nothing is a sure thing, but this is very, very close. You should be admitted with no problems, none. It is the repeat border crosser that is of interest to Thai immigration---one who does multiple border runs--crossing border and returning next day and doing that multiple times.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
