L2V, the shorts (on the whole) are some of the saviest traders out there. I wouldn't waste my time feeling sorry for them, if they weren't making money they wouldn't be able to do what they do. They have an incredible amount of patience and will often ride a short position up rather than cover.
An experienced short knows he needs to be even more diversified than a long. Often the short position is simply a hedge and won't be covered no matter how high the stock goes as long as the fundamentals that led to the short in the first place are still intact.
