During the months after I resigned from MOE eleven years ago, I once accepted a tuition assignment from a student hostel.
I went there to explain a Sec 2 History worksheet to a male PRC student.
After that I left. I was paid a few days later. It was very transactional, like a Grab delivery service.
This kind of job might be good for some people, but not for me.
I prefer teaching with rapport and a positive relationship.
