Possibly duty but - if it were me- not on the payroll - I wouldn’t give a fiddlers fart about the inlaws carol service
maybe they are better people than me- but thinking ahead- who will be king and queen in a few years and the royals doing engagements are advancing in years… they may be needed in time- I would like to see Zara promoted.
I don’t think you understand the position that royal family are in though.
sure, most of us wouldn’t give a crap about the in-laws and their projects/events. We’d maybe not bother to attend and shrug it off. Or we’d go to keep the peace.
but it’s not like that within the royal family.
1. they’ve been brought up and conditioned to venerate the monarchy and the monarch. Not the individual, but the office itself. They’ve been conditioned to want to stay as close to it as possible. It’s the source of their individual identity, their wealth and their status. If they decide not to bother to turn up to these events, they risk becoming irrelevant, or forgotten. They risk being pulled away furthur from the monarch. That’s something theyve been conditioned to see as unacceptable.
2. putting on a united front isn’t just for appearances sake. It’s a matter of security, safety and protection for them as a family.
in the past 100 years, monarchies that existed for centuries were ended. Sometimes violently. They’ve been made redundant, they’ve been banished. The royal family are walking on very thin ice. They can’t afford to not be the ideal, because that’s the only real way they are relevant now, amidst a torrent of reasons they are no longer viable.
