This comic reminds me of a few years back when I was visiting a friend. We were standing in her living room having a conversation. She walked off into a different room to get something to show me and just as she went around the corner I went into the kitchen. I then heard her walking back into the room talking to me when she suddenly let out a loud yelp. I rushed into the room and asked her what happened. “I was startled that you weren’t still standing there!” I think that’s the only time I have scared someone with my sudden absence.
