I've never been one for girlie shopping trips, ever.
The only time I enjoy looking at things is with my daughters because they have the same "OK, I've had enough, get me out of here NOW!!!" gene as me. So we can float for a little while, then it becomes necessary to go. I think why we do it together is because we are really the only ones who understand that feeling, so we are all prepared to leave once we get the word from one of us that we've had enough.
