Private island!

Jun 27th 2021

This is a private island. You might get away with walking around it, but some people hire out the entire island to themselves and since you won’t know when that happens, it’s only worth heading to the beach if you are a guest of the island - at which point I’m sure it’s lovely!

We landed on the beach by boat had been then about a hour and a wormen who claimed to be the land own pushing for a fight starting shouting to get off her land and very rudely started throwing all our stuff in the water and standing less then 0.5 of a meter away.

She wanted to call the police for us being on private land.

What did we get wrong?
