I agree with your reasoning. Just this past weekend I was with the in-laws who are all hardcore Dubs and don't know I know this religion is not the truth anymore.Anyways, they were always making remarks about future projects 10-20 years down the road and always adding rather ritualistically "If the end doesn't come first".
Hearing such remarks sevral times in the course of an evening can be quite irritating, and I would just add to that "Don't worry you have time for that project". Of course they would look at me with that "How dare you say that look?". And I would just remind them that with the unlinking of the 1914 from the "this generation" teaching in 1995, the end can come next year or in 10 years or in 100 years or in 1000 years. They of course look at me dumbfounded, and I get a chuckle out of it.
