You get so used to noises to check, you worry when you don't hear anything. d:o)
I still get up to check strange noises, "just in case". LOL!
Awwww....I guess it’s just part of the deal, but sorry you still have moments. I guess they will linger for a long time. I figure at some point in time, we will too.
Just like when our kid left home, and I kept listening for the hard rock to pour from his room. LOL! It was too darn quiet!
