Antonio Banderas Talks to a Donut
So you agreed to have lunch with a friend who wants to be more than a friend. But you're not sure you want to be more than friends. So you state upfront that "it's just lunch" and that when lunch is over, "this" will be over. All well and good if both parties understand.
However, if your date is a donut that just won't shut up and keeps lingering even though lunch is over, then you might need a bit of help from Wrigley's Extra gum. Hmm. If only things actually went that smoothly.
