@Xandrya I could tell similar stories regarding maturity. Drugs and alcohol can stunt growth. My father became an alcoholic when he was 19 years old. After two or three OUI arrests and 25 years at the age of 44, he finally kicked the yolk off. Mentally, he was still 19. The drug inhibited his brain from maturing. Undoubtedly your long board gentleman had a similar experience.
It was a bit of a curveball because prior to the date, I could have sworn he was more so the type of person I was looking for, but I was fooled. I have the typical drunk uncle who still lives in Cuba though and you can tell just by speaking to him he loves the bottle.
