Who Walks in When I Walk Out?

Who walks in when I walk out?
Who gives you that «hi baby»
Who’s it, who, got me jealous of you.
Who walks in when I walk out?
Now don’t you know you’re my baby,
Who’s it, who, got me worrying too?
Well, when we kiss, I kinda miss
Something that used to be.
Everyday, while I’m away, I get a feeling
That you’re fooling me.
Who walks in when I walk out?
Who gives you that «hi baby»
Who’s it, who, got me jealous of you?
