At first I thought, maybe get over it? But I didn't say anything because there are some situations in which getting over it is, and should be, impossible. I'm glad I held that thought because "sending a naked teenager (I don't count a towel as clothes) into the cold, without shoes, without finding out the situation, and especially when there could be a strange man out there looking for her" is an impossible to get over action, particularly if the person who did the sending has never verbally acknowledged her wrong or apologized for it.
Stand your ground.
