Public Service Announcement

I am going to start commuting with a small pair of scissors tucked in my pocket, so that when I see women who have not cut off the small X of thread holding the rear vent on their coats or jackets closed, I can just subtly bend down and snip it for them.
I thought that since winter was almost over, I wouldn't have to suffer through spotting instances of this outerwear mishap any longer, but noooo, out come the trenchcoats, and on stay the threads. Ladies, it is supposed to come OFF. The reason your coat pulls uncomfortably when you sit down? That would be because the vent is still sewn shut. It's not for decoration, you know. It serves a practical purpose. And the threads are just to help keep the shape of the coat on the hanger. Like when pockets are sewn shut. Ever thought to yourself, "hey, these pockets are just decorative--no, wait a second, if I just pull this thread...." Same idea for the rear vent.
Also, it's too late for lots of you, but you know the tag on the arm that declares your coat is 100% Wool? That should come off too, you tacky broad. I'm glad you're proud of your purchase, but that tag was to let you know the material composition of your coat, not everyone on the subway car with you. Take it off!
I am passionate about this. I have considered having friendly little chats with strangers to fill them in on the inscrutable ways of coatmakers. But it's a big world, and I'm just one woman....
