funny situation, you remind me my summer trip to spain when I was 25, I went with 4 of my friends and none of us understand a word in spanish, so in one of those hot day of august we couldn't fall asleep, although it passed midnight we decided to go down to the Hotel pool and swim, we enjoyed swimming for a while and suddenly a guard came shouting at us, no one understood what he was saying, one of my friend said we paid for this hotel so no one have right to chase us from this pool, the guard went and came back with another men, he was morrocan and he explained that a treatment have been added to the pool water and it is was bad for our health to swim inside it, so the next day we waked up with puffed red eyes
