Why are Alexis and Josh running away right after the ceremony?

After the ceremony, Alexis and Josh will spend their first moments as a married couple in complete privacy, alluding to the new intimacy in their relationship. Escorted by their dancing attendants and guests, they will walk from the chupah to the yichud room. ("yichud" is Hebrew for "togetherness.") Two witnesses will first ensure that there is no one in the room. Alexis will step in first and will then welcome Josh into this symbolic bridal chamber. The witnesses will close the door and stand guard outside the room, emphasizing that a married couple's privacy must be respected. For the nosy among you, the yichud room is really just a symbolic consummation of the marriage; Alexis and Josh will share a small meal (they will have been fasting all day until now), a few tender words, and Alexis will give Josh his wedding band in this quiet setting.
