Maybe not if money is tight? (or just that you're a cheap freeloader)
Money might be tight, if you are paying for an apartment and still need to provide for the family that you have agreed to separate from. You might also need some extra cash in case you run into any eligible singles who might agree to go out for lunch and a couple of drinks. Or if you can't suppress the urge to rent a girlfriend for a week or two.
All this while your financial support base keeps shrinking, for reasons that you just can't seem to grasp. Don't they understand what the life of a professional activist is like???
