a lot of modern teachers today not exactly the holiest saints around lor.
I once brought back a jc teacher i met at a club and she's those super chiong every week kind and worships angmo (SPG!). I also know of another lady who was the 3rd party in an engaged couple and they did all sorts of unwholesome stuff in the staff room toilet. all 3 of them are/were teachers. Dunno what happened after that or now.

But what i notice is that although their actions might be a bit unhealthy but what you notice is that they have the passion for their kids and that teacher 'fire' in them that they have when you talk to them.
