A couple of years ago a couple of elders, who are nice guys and are long time friends, came over to see me and invite me to the memorial. After listening to them, I asked them a question. I asked why in 1 Cor. 11:26, the scripture always used in the memorial confirming why they need to keep celebrating it, does it say at the end, to do it "until he arrives"? I said that other religions are not affected by that statement, since they don't believe Jesus has returned, but since JW's do, why do they keep celebrating it. I know the WTS has an answer for that they have concocted, but most JW's don't know that. They told me they would have to get back with me on it. Although I've seen them numerous times, it has never been mentioned again, and they didn't bother to invite me last year.
So, I have been waiting for my invite this year because I have another question. The JW's are big on having a great crowd of "observers" at the memorial, but where is the scriptural precedent for that? Seems to me if that was the way Jesus wanted it to be, he could have included observers.
