The best taste. [It felt very good to be wanted.]

There was this one day, when I was bored on shift, that I tried to think if I had ever seen her not with something red on. And then I almost spilled the drink I was pouring when I remembered when I had.

I find it very hard to decide which I prefer - her wearing red or not. [Lipstick clearly didn't count in this instance.] Think you might be able to help me figure it out?
