I wished her a Gay Christmas; so what is funny about that?

Look at the word gay; maybe, you were a bit flippant again?...haHAHA

Oh, I see what you're driving at. You had better take this word 'gay' to your English dictionary, and see what you can come up with. As for your other reply to me; I am now more convinced than ever that the only people who should teach oral English as FT's, should be native born English speakers. hehehe.
