My teaching contract does not forbid my drinking in my own free time. But I do ensure I'm not drunk in class. That said, back home my contract didn't say anything about drinking. Yet I was berated for it.
Anyway, I couldn't care less what your judgment of me is. I'll obey my contract here, which is me being moral, as I did sign it initially.
You come across as an antagonistic sort of guy. Well, no matter. I'm thick-skinned.
