Copy Cat behaviour

[DavidAJones]

I have a close adult friend who copies the behaviour of others in a strange and enduring way. Some little while ago she witnessed two children in dispute and one of the children thrust their face very close to that of the other and repeated foul mouthed abuse in short and repeated bursts of the f word three times in a very loud voice. When she is upset by almost anything, and it can be a very trivial matter, she responds with the precise behaviour. Even when her behaviour was explained to her in calm and rational terms she refused to recognise that there was a problem. There are other similar examples of this emulation of behaviour. It it a recognised condition?
