Question
Why is the afikomen taken from the middle matzah during the Seder rather than from the top or bottom matzah?

Question
I work in a Jewish institution which employs a large number of non-Jews. Actually, I am the only Jew in the office. We all share a communal fridge and various snacks. It is assumed that if something is in the fridge it is for everyone's consumption. I brought in a container of peanut butter and leave it in this fridge. Must I take it out for Passover? Wouldn't taking it out be saying that it really is mine, even though I do not feel that way? I do not want to remove it and have people think I do not want them to use it. Although everyone seems respectful, often I overhear colleagues saying things like "that Law is stupid" etc. They are not being hateful, they just do not understand, and I would not want to do something that might incite any form of hatred towards my traditions. My immediate supervisor has a private fridge (he is Christian). Would a solution be to ask him to hold the peanut butter in his fridge for the week? Please advise. Thank you and chag Pesach kosher v'samaich!
