Because your son always tells the truth to his parents. He never would have lied to hide the neverending foam parties, scuba diving while still half drunk from the night before, the hospital visit after trying to pet the jellyfish, the hopping from one bed to the next, the bicurious incident, the chlamydia treatment, the midnight joyride through town up to the beach at high tide, or the following hangover in jail. And if he's still pasty white, it's not because he lived the life of a coked-up night owl, it's because he stayed in his suite all day and all night watching stuff on his laptop.

Maybe he has that stereotypical pasty British skin? Otherwise, he probably hired a string of hookers and watching crap on his laptop was just a cover story.

It could be he wanted vacation away from friends and family just to have that alone time. If he used his savings for the trip, then it is his choice and doesn't have to make sense to us. Sure I'll not spend that much to spend it all on pornhub disguised as netflix. But to each his own.

Did he spend HIS money to get there? Then drop it. Sometimes people like to just 'get away', not necessarily be tourists. Even if it was your money, if you offered it stipulation free, then you still don't get a say in how he spent his time.

Maybe he just wanted to get away from friends and family
