The things HAM say to praise each other do tend to be very, very odd.
Harry: She's really hot, and such a massive star that my family were starstruck by her.
Meghan: He's a fox and he loves me loads and loads.
These just don't seem to be the kind of things people normally say about their partners. It's weirdly shallow and clunky. There's nothing really about the other person.
When I compare them with (for example) William praising Catherine for being an amazing wife and mother and for getting expert knowledge on her Early Years projects. Talking about her making her first solo international trip after overcoming cancer. And saying that their family couldn't cope without her. It's praise which actually has some substance to it. It's about her as a person and what she does.
