You were somewhere — with someone, in some situation — and even though nothing obviously bad had happened, a feeling crept over you that something wasn't right. A discomfort you couldn't quite explain. Part of you wanted to brush it off, not make a fuss, not be rude or weird about it. But the feeling wouldn't go away. You didn't have proof. You just had this quiet, insistent sense — that small voice that says something's off here — and you weren't sure whether to listen to it or talk yourself out of it.
