Thanks everybody, how is it we can see what the term generation truly means but the JWs just don't get it?
Getting back to the baby chair; When the chair had been in existance for 23 years and kept in the same family (let's call them Mr and Mrs Overlap) and handed down is it not logical and obvious that only a new baby generation could sit in it because the original generation for whom it was first made had got too big for it and were creating the next generation. Who but a new generation could sit in it after 23 years ?
The overlapping theory is just plain stupid!
