I thought you were lost...

So, last Friday I went out to mow the front yard one more time, since apparently Fred isn't going to start the mower up any more this year. The kids had just gone down for nap, so I thought I had plenty of time. When I came in Jacob was already up from his nap. He had turned on the TV and was watching his shows. He looked at me and very non-chalantly said "Oh, I thought you were lost." He turned back to watch his shows, showing no sign of relief or excitement that I had been "found".
