A total stranger asked me how my day was going. I was waiting for my double espresso, and I think he'd just finished paying for an iced coffee. Being a generally social person, I was immediately pleased that someone seemed to have at least a modicum of genuine interest in my welfare. This initial reaction was then slightly tempered, in the following three or four nanoseconds, by a cautious optimism that overtook me as I began to consider the distinct possibility that this seemingly harmless gentleman was, in fact, some sort of raving lunatic...

...preparing to pounce on the opportunity to get external validation from me, his next hapless victim. As it turns out, he was either a real gentleman or an outstanding actor. If forced to bet, I'd guess he wasn't acting, at least for the most part (note: those relationships closest to us present the greatest challenges for personal growth. Consequently, random social engagements, given their comparatively superficial nature, are generally much easier to negotiate than the relationships we have with a spouse, close sibling, parent, or child).
