I should have expanded my answer. If it was human nature for him to just walk into the house, he would have ALSO done it when his exwife was there.<quoted text>??
That makes absolutely no sense.
So he goes to pick his sons up. At a house that was his home for over a decade. And its only human nature to want to check the place out if she's there, but since she's not human nature is to not want to look around? WTF?
I'm not saying he has a right to go snooping around, but its human nature that he wants to check the place out. Her being there is a hindrance to him acting upon that. Which is fine.
Hell, when I got married and moved out of my friends house, I had the same kind of curiosity whenever I went over for a visit. Curious as to what's different from when I was there. I didn't act upon that curiosity and go wandering into bedrooms, but I certainly noticed anything that was different.
I thought you were saying it was human nature to have the habit to walk into a house you lived for so long. I didn't realize you were saying it was human nature to have that curiosity. That's not a good enough excuse to go into someone's house -- because you're curious? No, he's an ahole is why he did it.
I'm curious about many things. I don't act on all my curiosities.
