What kind of assumptions...Einstein's creativity center immediately started churning up ideas. She blurted them out without thinking. "We're spies. Or cops. Or lovers. Ooooo. So, one of us is married, and gay, but secretly, and is having an affair with the other one, but is also planning on admitting it soon, so is comfortable with meeting in public. Or because we're also known friends, so it's not suspicious to be out together." Random thoughts. Although that last one gave her another idea. "Or maybe we're just two friends having a normal, quiet conversation in an equally quiet coffee house."
