Ever encountered someone with a poker face that exudes an air of indifference or aloofness? It's called Resting Bitch Face (RBF), a facial expression that often gets misinterpreted. Instead of directly asking, "What happened?" you can subtly engage by adopting a similar tone. RBF isn't necessarily a reflection of mood; it's a neutral expression that might conceal a multitude of emotions. So, rather than prying, try conversing in a manner that mirrors this nonchalant demeanor.
