How do you feel about people walking through your campsite?

We had a funny experience this weekend. While sitting outside we heard loud voices in the woods behind us. About 8 adults and kids came out of the woods into our campsite. They seemed to be quite inexperienced hikers (flip flops) and had gotten lost. They were tired and thrilled to see campers. They kept telling us they were so sorry to walk on our site. We were all laughing together reassuring them it was fine and asked if they needed anything. They just needed to find their campsite.
