During my practicum twenty years ago, there was a General Election. It was Prime Minister Lee Hsien Loong's first GE since he assumed the office and the air was buzzing with excitement. This was also the GE when James Gomez of the Workers' Party had an incident about a form.
One of the senior colleagues in the school, a vocal man who had been in service for many decades (he was always telling people that) told me, "I support the PAP by voting for opposition". He meant that he wanted the PAP to work harder.
At that time, I was quite pro-Workers' Party and attended one of their rallies even though it was across the island. It was people mountain and people ocean. I saw one of my colleagues from my practicum school and called out to her. She was a Chinese Language teacher and I called out, "Teacher ___________!" in Chinese. She looked very pai seh. She probably did not want people to know her job.
Attending a WP rally at that time felt like an act of rebellion...Not so now.
