I find it unbelievable that anyone would actually stop you. They might talk to you afterwards but come on..... Would one of those little priesthood guys tackle you? Would someone yank you out of the pew? I'm at a place where I just plain don't care about that kind of junk. Just take the sacrament and see what happens. And then keep taking it even if someone does notice. They have given you more than enough heartache so give them a little ridicule. I'd make odds absolutely nothing would happen. I dare you : )
