The unemployment rate is so high in Cuba that there are people living the 'Life of Riley' morning, noon and night. They're always going someplace, going to see someone about something and trying to get something going. Most times fruitless. The successful ones have small black market enterprises flying under the radar. A hidden beauty salon, seamstress shop, room for rent.
The late afternoon brings about the same kind of activity seen here in North America: Buses full (much too full, if you ask me) of people going home, ladies picking up small groceries, uniformed school children coming home, spouses meeting each other at the end of the day. The universal effort of all people everywhere trying to better themselves.
If a 'turista' meets a girl in Cuba and wants to spend some time with her, it's like winning a small lottery jackpot for that girl. They know most tourists are only there for a week or two so they'll break all their own rules to spend the time. The hope is that you might buy them some new clothes and groceries. Take them out to dinner someplace they could never afford. See the inside of the hotels they can only gaze at from the outside. Get spoiled a bit. In their dream scenario, you will marry her and get her out of Cuba or at least send her monthly $ so she can hold her head high and live a better life. Cubans have very little so they need to invent everything.
As I mentioned, be aware of the societal conditioning of this gorgeous island and it shall be your kingdom. Give back to it as much as you can though. It'll pay you back affectionately and warmly.
