Janis: Notice anything?
Arlo: You got your hair cut!
Janis: Yes, but I didn't get it colored! I got streaks of highlights instead!
Janis: I'm transitioning to natural gray.
Arlo: Cool!
Janis: Arlo, this is a big deal!!
Arlo: What's a big deal?!
She should understand that relatively sane men, to one of which Janis is luckily married, as they age, discover that women they used to consider old as their granny can be hot. Colored hair, in a woman obviously beyond the grey age, is ridiculous. And I believe Arlo’s attention to what occupies at least 2/3 of his brain has kept him well aware of her natural hair color. (The other 1/3 is occupied by the cat and his various goofy ideas.)
