Shitty male character: Getting suspicious of his shitty lover.
Me cackling: Get f*cked you shitheads
I find it funny that 7-year-old Hailey is afraid of the inexorable march of time. That's heavy for seven.
I don't remember where I read it but a few years ago there was someone telling a story about their 13-year-old and his 5 (6, 7? very young) sister having a mild existential crisis together after dinner. These kids discussed how the body needs oxygen to function and then the oxidisation deteriorates it, leading to death. Maybe not scientifically accurate (or it is, I'm dumb either way) and I only vaguely remember the gist of that post now but I think about it at least monthly.
I'm also open to the fact that that story is entirely fiction, but I think it's not too far fetched that some kids are just so observant beyond their years.
