Youthful survival skills. I'd wager there are a lot among this crowd with a story like that.
Coats, whilst quite fashionable and almost never a bad choice, don't always do the trick. Or so I'm told. It's not much of a concern. Seeing as self preservation is a honed skill of yours, I'll assume you know what you're about.
Don't be obvious and I won't make a show of watching. It's a wonder we've never spoken before.
