To see the beautiful faces of all the nuns I taught ESL to (really English as a third language). They have made me discover what my mom said often but I never saw at home: joie de vivre. The nunnery was paradise to me.  Their tolerance to my smoking was remarkable though I dont even want to think of the bother fuss for them that created. I really dont think it is a sin to smoke cigarettes. But it is one filthy habit and addictive for me like you can only imagine.
