They said they don't get many negative comments on their own channel so they might be addressing Tattle, although they referred to things we haven't really discussed eg lots of freebies, them arguing, and presuming they are mates with all Youtubers. Maybe people discuss them elsewhere, on expat or local commmunity forums, or forums for content creators. Or were they simply trying to hush local gossip, after all the recent dissing of crowded Positano and pesky tourists prompting her purchase of the Tuscany house? It's strange that people think they can tell you what you should think about them
I'm pretty sure Carlo's retirement was planned for the time it happened, quite a while back they said he'd been at the cemetary job since he was very young and had served the requisite number of years. If he had an olden days muncipal pension it could well be on full salary, so no one would blame him for that, good luck to him. I still believe he's a genuinely warm person who enjoys the strong ties he has to his local community. In the past she used to film him more incidentally, doing things around the house, coming and going from work but I think she's using him more since his English has improved and she knows he's more likeable - and he's stepping up because she calls the tune.
