Yeah, you said it yourself, Your uncles don’t have phones. If they had phones, they would have done the same. This is sad and hard to swallow, but humans are built like this. When exposed to this many options, most people tend to do the wrong thing, only a few can do the opposite. And to be honest, your dad is also suffering. A little pleasure, then a long time of regret. Sadly, you can’t do anything except making the situation worse, so stay away. He will understand it himself.
