The Exodus from Egypt.
Jews.
Jews eat the Passover meal to commemorate what happen to them a long time ago. In the Bible, it explains that the Jews were taken out of Egypt, in a hurry. Their bread did not have a chance to leaven, and so they ate what they call "matzoh" Now Jews have a meal with "matzoh" in it, to commemorate it.
Generally it occurs only during Passover, a Jewish holiday. There is also a seder for the holiday of Tu Bishvat, but this seder is rarely observed.
The hands are washed twice with water during the Seder; once shortly after starting, and once right before the meal itself.
It depends entirely on which special meal you're talking about. Every Holiday except Yom Kippur has a special meal or special foods eaten. Shabbat also has a special meal, as do certain occasions, such as funerals. Jews do not play games during meals.
Jews dont.
The evening meal for Jews has no special designation.
Pretty much what it means to anybody else. White bread used to be a luxury food, eaten only by the rich, while poor people ate whole meal bread; so Jews ate white bread for the Sabbath, if they could. Now that white and whole meal bread cost the same, and white is no longer seen as a luxury, those who prefer whole meal have it on the Sabbath as well as during the week.
The Haggadah contains the service for the seder.
The word 'seder' is Hebrew for 'order'. The Jewish Seder is the ceremonial meal in Passover, during which, according to a set of ancient customs and text, we recount the Exodus from Egypt.
The ancient Jews did not have any special meaning to sharing a meal. although, the Arthur Shai Agnon- a Jewish-Israeli who won a literature Nobel prize- used to describe sexual interactions with "sharing a meal". it has nothing to do with ancient Jews, but maybe that's why you had that in mind.
