It’s time we all sat down and developed some rules for this exact situation that happened to me earlier.
Someone asked me for directions to the same place that I was headed to. We were too far away from the place to walk together in a way that I felt acceptable between two strangers. My directions were very vague and I had to watch him ask someone else for better ones. Then, at the venue we are stood next to each other at the bar and he sees me and clearly thinks why did that guy seem so vague when he knew exactly where I wanted to go. The whole thing is just too awkward for me to handle.
