It is always preferable to visit home with a friend. Your parents will
not be pleased with this plan, because they want you all to themselves and
because in the presence of your friend, they will have to act like mature
human beings.
        The worst kind of friend to take home is a girl, because in that case,
there is the potential that your parents will lose you not just for the
duration of the visit but forever. The worst kind of girl to take home is one
of a different religion: Not only will you be lost to your parents forever but
you will be lost to a woman who is immune to their religious/moral arguments
and whose example will irretrievably corrupt you.
        Let's say you've fallen in love with just such a girl and would like
to take her home for the holidays. You are aware of your parents' xenophobic
response to anyone of a different religion. How to prepare them for the shock?
        Simple. Call them up shortly before your visit and tell them that you
have gotten quite serious about somebody who is of a different religion, a
different race and the same sex. Tell them you have already invited this
person to meet them. Give the information a moment to sink in and then
remark that you were only kidding, that your lover is merely of a different
religion. They will be so relieved they will welcome her with open arms.
