Imagine what he's like at a parents' evening (or afternoon). Wittering on about how school was better in 'his day', casually dropping in references to his A-levels and sporting achievements, bragging about what an amazing father and massive overachiever he thinks he is, making it all about himself, harvesting the session for things to moan about or anything else he can use on instagram later. Wouldn't even surprise me if he tries to get away with surreptitious photos and videos inside the school.
