Is it weird I don’t know how many siblings I have?

So I have at least 2 half siblings and at least 4 step siblings! However theirs one possible half sibling who was never confirmed to be my fathers child! Their could be more since both my mother and father have been in multiple Marriages and my step mother has children in multiple countries (because her children have been very successful and had to move because of work) so I don’t actually know how many kids she has and I’m not gonna ask.

So the question is this: Are my circumstances weird/unbelievable Or is this one of those things you never bring up when drinking?
