SaucyJack - the problem is man-listening
Here is what the OP said, juxtaposed with the interior monologue that prevented him actually hearing it
"DP, I'm really ill today."
She's struggling a little with a minor touch of something, that is nothing much, but women are lightweights, bless them, and a bit moody.
"Please come home as soon as you finish work"
Ah, she probably wants me to go for a little stroll to get her something nice to cheer her up. She said "as soon as you finish" but I am a man, so I know she would prefer chocolate really, because men always know best. And women love chocolate.
"because I'm struggling to look after the children."
Also, it is, let's face it, it's more my real job to bring Things! to the Cave! than actually stay in the cave and look after actual children. She probably isn't struggling at all, because it comes naturally to them. I would struggle though, because it's hard when I try to do it, because I'm a man. Much better for me to hunt and slay some chocolate and radox and prove myself that way, than do what she actually asked me to. And as I know best, she will actually prefer it! And then I get to stay the good guy too. Only a bitch would fail to recognise my great good intentions. Which are the main thing. What I feel, and mean, and think. Yes, those are all the important things in this situation. Off I go to get chocolate, hurray!
