My wife mentioned the Memorial for the first time today! She didn't ask if I was going, she only said that she was going...My son was around so I said innocently: "I work with a Jewish girl and she told me Passover starts on Friday night", to which my son replied: "the day starts after sundown" to which I replied: "Jewish passover starts after sundown on Friday so Jesus would have celebrated Passover on Friday night and not tonight"...big silence, then my wife said: "Well the Memorial is tonight!" My only comment was: "I don't really care on which night the Memorial is, I just know that the Jewish Passover Jesus celebrated falls on Friday and not tonight".
I had hope that my comment would have them question why the Memorial is celebrated a day before the Jewish Passover...and question why the speaker will say that on this night some many years ago Jesus ate his last Passover meal with his disciples...but I guess the WT "scholars" must know better than the Jews when Passover is celebrated!
