Hey oppar, I’m on a group trip to Japan. Everyone is perfectly lovely besides this man (31 years old) on the trip. He’s not a bad person from what I sense, but he is a hot mess. he’s got ADHD + Autism (or so he claims) and so he acts out a lot. Like he’s always running late for trains, too loud, like attention. He’s also a bit too touchy-feely for my taste with the girls and flirty. I think he gets away with it because he’s handsome.
He has referred to himself multiple times as “Japan’s Sexiest Man”.
One of the other women told me he was insecure, but I don’t really care? Like why do I need to babysit an adult man? And I especially feel there is a double standard. No way anyone would tolerate a woman in the group acting the way he does.

Nevertheless, he’s an entertaining mess though so I feel like most of the group likes him simply for that factor. Even though he greatly annoys me I feel a lot of empathy for him because he had a rough family background and there’s this sort of sadness about him. Like he’s putting on a happy act.

We don’t get along well so there’s this weird dynamic where half of the group interacts with me, half with him, and some both.

Should I just be more empathetic? How do I talk to people like this? The trip isn’t too much longer and so far I’ve just been politely keeping my distance.
