My autism in conversation

When I arrived in Fiji and had been collected by my host, he asked me if I was vegetarian, I pointed out that I was not but could not eat Gluten Free food such as wheat. I also said that I couldn’t have honey. I didn’t want to mention that I don’t have dairy as well as I have been bought up to try everything that is put in front of me. The conversations I have had with my hosts have been hard as I have not found the opening where its not stitled and when I bring up certain things the conversation dries up and it seems like a piece of tumble weed rolls through the house.

The first night I had been chatting to my hosts and I asked them about their heritage and they said that their family had been bought over by the British. I did not know what to say in response. I felt tarred by stupid history that I don’t know how to respond to. At tonight’s dinner I met other people who are staying at the Airbnb. They had not let the host know about any delays of travelling, contact was made this morning and my hosts were unhappy however tonight it was a different story american who knew how to sweet talk his hosts about praises to their food and Australian girl who had travelled to India for a few weeks. My hosts were lovely and chatty to them.
This an autistic problem of social interaction that I am finding hard to know how to deal with
