and NOT something a man of almost 50 would need to be sat down and given instructions on?
It has never ever occured to me that Himself does not do this. Ever.
I have wondered why all of a sudden, my bras go grey or the kids' pe tops go grey.
I've blamed the washing powder, the machine, poor quality clothing...
But today I find out that when Himself bungs a load in the washer, he just grabs whatever is in the washing basket and lobs it in 
My last white bra is now disgustingly grey.
I mean, when I do the washing, I separate it. He has walked into the kitchen before and found me sitting on the floor putting the dirty clothes into piles - wtf did he think I was doing that for?
It honestly never occured to me that he is the reason I have dirty grey manky bras and that a grown man would need washing lessons.
AIBU? Naive? Thick?
