You may have the impulse to be confident and say what you mean on monday, but the reality of the situation is going to require you to be a bit more circumspect. Sometimes the circumstances just aren't appropriate for flirting, even when both parties are clearly interested. Don't worry. You'll be able to make your big move (even if it's just blurting out a simple conversation starter) on tuesday or wednesday. Remember that love takes time. It's unrealistic to expect to be married by friday. But keep in touch over the weekend. There's a fairly good chance you'll spend sunday flirting on the phone for hours.
