Choosing the best man, might be the most difficult part of planning the
wedding. You must choose the best candidate, without hurting anyone's
feelings. The suitability of the choice for best man, and their ability
to perform the tasks at hand is the most important issue. A great deal
of responsibility will placed upon him, especially at a large wedding,
and it would be unfair to ask anyone to take on the role, if they were
not capable of handling the task.
