I have recently just started nodding in agreement and changing the subject as I'm finding it terribly frustrating.
For context: Friend's child outwardly boasting and being rather obnoxious. I point it out as other kids are getting a bit tired of it. Parent of said child has fully witnessed yet insists another child must have provoked such a reaction somehow.
Child rolls eyes and says "Oh no, not chicken again for dinner!" quite comically to which we all laugh, so quite memorable. Subject comes up again and parent insists child didn't say that, only the other kids moaned about the dinner.
Little fall outs over toys etc. Parent insists that it couldn't have been their child as she wouldn't fall out over toys.
A mildly rude word is said by child which adults hear, all kids giggle etc. Parent insists another child must have encouraged him to say it etc
All small stuff, but beginning to get terribly irritating and frustrating.
Am also thinking how on earth will the parent cope when they finally realise that the child isn't an angel.
