First impressions can be misleading.

It's not uncommon to meet someone who might come off as cold or standoffish, who turns out to be genuinely kind and innately likable.

Or, on the flip side, meeting someone with an effortlessly charming public demeanor, who might be a little less charming behind closed doors.

But every now and then, there are clues from the moment you meet or first encounter someone which gives a clear idea of their personality.
