This is what my face did after my husband snuck silently and unnoticed into the bathroom while I was taking a shower, only to stand outside the glass doors menacingly until I turned around and discovered him there.
I screamed at full volume not once, not twice, but three times before collapsing against the shower wall and dissolving into hysteric tears. It took me over 20 minutes to stop shaking.
Needless to say, I'm pretty positive he's been permanently cured of his desire to scare the pants off me.
