Okay How Do You Southerns Do It?

(The parchment appears to be spattered lightly with ale and the handwriting unsteady, clearly written while intoxicated.)

My suggestion Jack,

Stop wearing bifurcated leg warmers. Why wear pants when you can be civilized and wear a kilt? Wonderful, all-purpose garment that it is, its warm in the Autumn and Winter and cool in the Spring and Summer. Plus, its wool, so you won't feel awkward in Southron fabrics like linen and cotton. Get yourself a Kilt, burn your pants and never look back. Trust me, you'll thank me in a matter of minutes.

Recently, I woke up under attack, got really angry, and found that my blood got heated up almost to a boil. I felt fine, but it did get uncomfortably hot after a while. Probably ruined my leather vest. After that, I don't think I'll be complaining about the heat any time soon.
Not that I am recommending your solution being heating your blood to a boil. That is a bad idea. But it does make sense why I see so many angry northmen! It's certainly a good way to keep warm!

Sincerely,

You endure it, cousin. You let the heat ignite your anger and you sit beneath a tree, like a dog waiting for its pack.

That or you do what I do and spend most of the time wearing a vest and nothing else. Or make some fancy elf hold your furs, I hear that works too.

(The parchment is ale-stained, written in a very shaken hand,) stay inside the taverns and inns of the proper, dae a proper pub tour, and keep ooouta the heaaattt until da dark falls, then wear an hat. If ye don't wanna do eeeit, stay under a tree like the Druids and dryads....rspct.

Dimms,

Find me, and I can show you good trees to rest under. It's better than boiling under the hot sun.
