@snood,
I don't have a handle on the variety of people who came here as Dreamers. I suppose Mexico is only one of the many places, but it's a country I know better than others.
Immediately I think of old friends - in no special order: Nagi, an egyptian man who fled Nassar, that I met when he was a med student in Guadalajara hat met at the Hilton Bar, this in the sixties, and some stayed friends). Far as I know, he's still a practicing doc in Orange County, CA. or likely retired.
Sergio, a fellow from Chihuahua, Mexico, studying at UCLA. He dated one of my girlfriend group. My girlfriend group, including his girlfriend, went to Europe (no way I could afford it), so I helped him with his English.) No dummy...
Sometime later we all met back in Guadalajara. He took us to the university carnival, among the better times I've ever had dancing, the room rocking, guys with tubas exploding the air around us after they entered the auditorium.
A2k's Pantalones. We haven't caught up since Christmas time, but will. Now there's a bright person.
Luis, whom I miss on a2k a lot.
I could add a lot more.
Most of those were people with both good brains and access to good schools.
