I think it was a sign that Jake should stay.

As for the locks - after I wrote I realized there actually are locks, we have just never used them. In the entire time we've owned the house! So - we'll see if they work and see if we can find the keys.

We're not the only ones who don't lock the doors, I guess - the cops called to say they found the intruder inside somebody elses house! I'll bet they start locking theirs after tonight, as well!
