Second thoughts

Do you ever feel out of your element? I'm planning a trip with Debbie and I'm starting to be worried about it. It's months away but I'm starting to worry a lot. We'll be hanging with a couple of our friends who are really way out of my league. Debbie can fit in better...she at least can speak the language. I have very little knowledge about the subject or similar ones. I'm starting to wonder if this plan is a mistake.
