Unnoticed

The phone rings. Husband picks it up.

"Hola?"

"Hi Rob, it's S-. May I speak with Julia?"

"Julia left a while ago, I think."

"No I didn't! I'm here!" I yell from downstairs.

"Julia was there but you didn't know it?" Laughs S-.

"Wow. I guess not."

How can you not be aware of someone else's presence in a 1,000 sq. ft. loft where every snore, gulp, or hiccup bounces off the walls? I guess I need to start wearing a bell around my neck. ;)
