You may forget, but writers are people. We have lives, we do school, we go to work at seven o' clock at night and then stay over the weekend!!!
But that aside. Writers have this weird, dynamic angle that lets them see the same thing you do, but see it in an entirely different context than you. Much the way that humans see snow as a nuisance, and dogs see it as white fluffy cold stuff to bounce around in...
In a slightly more sympathetic instance, if you see a flower pot you see a flower pot. I, on the other hand, would automatically assume it's either a magical hotspot for those pesky mini-gremlins that infect the wall, or a misused helmet mold for the warriors of the Farway Realm of death.
Oh dear, dinner just got called. I must depart, but LET IT BE KNOWN!
WRITERS ARE PEOPLE, WE'RE JUST WEIRD!
Fail for this being a long-though-out post but being short anyway,
