Sometimes when you're traveling alone, it's best to just say yes.
Today, I found myself chartering a boat with a group of three Chinese people, and three Brazilian girls. We had two skippers who drank the whole time (clearly they are functioning alcoholics), and at one point, we all shared a joint.
We just did a little island hopping and hung out all day. Quite fun (mis)adventures, and a nice end to my stay on Hvar! (Not to mention the lovely sky as the sun set...)
