Wow you really earned a lot and spent a lot too. No way could any teacher do that on a teacher's salary. Saving a grand a week is more than most teachers earn a week. The most I earned as a teacher was £750 a week when I had my own limited company. We lost all that money because we weren't working and we didn't buy a business and we were just spending money on accommodation and living expenses for 3 years. Between two people it's easy to spend all that money over 3 years really when you're not working. Thailand isn't that cheap when you're not working.
