Watch out, Receiver. Trouble lies ahead, for both Bearer and Receiver; Danger constitutes an unequivocal warning to think very carefully about the possible consequences of one’s actions. Whether sent in the context of an ongoing hostile exchange or a serious conversation, it is always advisable to pay attention to the warning contained herein. Responses vary from the disbelieving WTF? or You've gotta be kidding me to the puzzled You intrigue me, the possibly foolhardy I can take it, the passionate I'll do anything or the dismissive Whatever. Fear communicates fear and acceptance of the Bearer’s warning, while I think not denies its validity.
