Send (*^▽^)/ for the mun to give your muse advice and/or gossip about their relationship with my muse!
Tbh, I don’t think there’s much or any advice one could give to Mo! As different as both Antonio and Mogens are - in both personality and their views, they’re somehow able to form quite a formidable friendship.
Antonio really appreciates their friendships and he often enjoys hearing what few things Mogens has to say - he finds his words and view in life rather insightful and allows him to gain a better understanding of the life Mo leads. In turn, he hopes he’s able to somehow impact Mogens’ life in someway, even if it’s just being that one guy who’ll greet him on a day-to-day basis.
I think he trusts Mo a lot more than he lets on, and would probably tell him a secret or two considering how Mogens doesn’t seem the type to gossip, really - at least, not without gaining something from it. But he trusts him enough to know he wouldn’t ramble about his personal life with others (not that it matters seeing as Antonio does that a lot, himself).
Overall, there’s a good amount of trust there and a lot of a surprise factor, I believe. He can’t really read Mogens all that well and it seems to work out despite all that! He’s really happy to have bumped into him at that coffee shop.
