Dinner Problems

I was invited to a stranger's house last weekend. I did not know these people, they may have been very nice, or they may have been psychopaths. But, I decided to go, since I was invited. It’s always nice to be invited. I arrived at the specified time. There were a lot of strangers there. It seemed kind of weird; I had never been to a house like this before. What was even stranger is that these people, who I didn’t know from Adam, asked me to eat with them. Now, I’m not a paranoid person, but I don’t know who these people are. I don’t know if they know that I don’t like certain foods, or even if they know that I am lactose intolerant and have a deadly peanut allergy. On top of that they are serving something that doesn’t look like what they say it is. How can I trust these people? They are so danged persistent that I eat with them. It’s really weird, and very awkward. What should I do? I mean, it was nice to be invited, but I don’t think I want to eat what they say they are eating. I’m not even sure if I believe they are eating what they say they are eating. What if I’m allergic? What if it’s laced with poison that they are immune to? And why are they so danged persistent? This must not be a very important meal if they have to push it onto people. Ok, I’ll eat it, but I’m not coming back the next time they invite me!
