Do people not understand social cues. Like I'm clearly irritated. So lets stare at me and acknowledge i look mad . Or I'm not in the mood to talk so just keep talking even thought I'm clearly hinting I don't want to talk. Like seriously ? Or ask me personal questions and I nicely make it clear I'm not interested and they just keep asking questions ... 😣😡 I can't anymore.
