There are many milestones in a dating relationship. There is the first date and the phone call arranging for a second date. There is the date at a favorite pub and meeting friends. Then, there is the all-important dinner party date. A couple invites their friends over and cooks an entire meal for them. This is an important date because it shows whether or not the couple can get through an event together.
Cooking the meal together is often a challenge for a couple. If there are a good number of guests, it will show them how well they can cooperate while sharing appliances, keeping track of time and getting the table set perfectly. Once the guests arrive, the couple must play the perfect hosts. The couple must also deal with cleaning up after the guests have departed. If the couple can get through this evening together, they are well on their way to a serious commitment.
