DD went out to her friend's 18th birthday celebrations last night. I think the group all had too much to drink - and DD had a falling out with one in particular. During the argument, DD pushed this other girl lightly. No harm done, no one was hurt or fell over or anything like that. Upshot is today, other lass is threatening to report DD to the police. DD is now worried sick of course - she's normally a reserved type of person and has never been in trouble for anything before - never mind anything like this. Any advice? Are we likely to get a visit from the police over this? Thanks in advance.
