The name tag question made me think of another discussion we have every
whether to issue what we call carnets de bal, ie: a program with room
specially to write the name of the partners you invite or are invited by
for each dance.
Some say, if everyone gets booked up before the dance even starts, some
people that are nervous of inviting others, or who don't know many people
at a dance, are going to feel left out, find themselves stuck all evening
with partners no-one else wants, or find sets are all made up by the time
they have made the rounds of the wall flowers.
Those in favour of choosing partners in the early part of a dance, find it
is a good way of going round, breaking ice, renewing old acquaintances etc,
in those sometimes awkward moments while the band is still tuning up and
others are still arriving. It also means that sets are indeed made up more
quickly, as soon as the MC has announced.
Personally, I think it's a god xway of getting people to mix and discourage
them from keeping to their favorite partner.
