Again, really not defending PA and if this indeed took place, there is no chance whatsoever that his security detail or secretary doesn’t have this noted down. I don’t think it happened in the first place, I think it was a lie.
However, from the other parents, you never know. Many children invite the entire class and in some cases the entire year. Before Covid there were a huge amount of parties for our three children, logistical nightmare to get them to places (they go to school with wealthy /famous children, we don’t even have a cleaner). Some parties have been in amazing places (I remember a ball room
), some parties have been very low key, pizza express style parties. I remember a particular ball room because I have never been to such a nice venue myself. I couldn’t tell you which parents were there apart from 3 mum friends who I was talking to about the amazing venue. I couldn’t tell you which year it was but I know which child who attended and the child hosting because it was so special.
To be honest, I always think it must be so hard for famous parents to be recognised. I chat to parents of DCs close friends (none of which are famous) and nod to the others I recognise. Assume that the York girls get invited to 20 parties a year. This is probably very low since some parents will invite royalty especially. If PA occasionally pick up/drops off that would mean that parents would bump i to him at school gates, at sports events and at maybe 10 parties a year - for each of the girls assuming no overlapping friends. The novelty of someone famous wears off. Over several years, it may be tricky to say for certain which parties he was at, especially a long time ago.
But again, there is no chance that security detail /secretary won’t confirm, so maybe it is a moot point. I am just saying that just because parents won’t remember it doesn’t mean it didn’t happen.
Besides, as PP pointed out, what stopped him from going out after the pizza party if he indeed was there?
