To think child should have been told this years ago?

[Connected1]

So, friend (let's call him Al) married Bea, then got divorced after 6 or 7 years
Al goes on to meet Carla, they have a son David.

David goes to the school where Bea, his father's ex-wife is teaching. I always assumed that David knows all about Bea.

David is now 11 years old and Bea is his teacher. I just found out today that David has no idea that his teacher is his Dad's ex-wife.

Al plans on telling David about Bea when David is a teenager. I think it's crazy that David hasn't known about this since he was little.

I think he would have just completely accepted this as its no big deal. But not telling him makes it seem like it is a big deal.
Am I being unreasonable?

Nobody laughed at the murder of your grandmother.

But making such stupid comparisons between finding out someone in your family was murdered and finding out that a parent <shock horror> had a relationship before your other parent is laughable.

I have no sympathy with these people who take this kind of information and make it all about them. Nobody was ever lied to, her parent had a relationship with someone else once, much like the majority of the population. We need to stop pandering to this kind of crap and letting people think that they’re being lied to/that something like this should screw up anyone’s life and make it clear that what happens before is nobody’s business.
