IN: Concrud ? Not me ! This year I survived all events without getting sick right after . Not my cohabitee though . She brought the ever popular snot plague , and of course , the day she got over it , it started on me .
Why did I eventually get sick ?

OUT: I caught something from my roommate .

IN: He was really nice and patient and said that he wanted to keep me as a customer . So , they will reimburse me for the cost of the new hard drive that as installed by the third party they sent me to , and they will also replace my optical drive , which went down right after the warranty expired . This made me feel better , and renewed my faith in Mac . I have remained loyal since 1984 , and it 's nice to have my loyalty and faith restored in at least one area . Also , I got a nice note from Tanya who is half way round the world doing fieldwork .
Why did Mac decide to reimburse them ?

OUT: They wanted to satisfy them as a customer .

IN: One of my favorite parts of CharityFocus model is that it 's demand pull . We do n't have to waste our time predicting , because we 're always half a step behind our amibition . Or as I once said to some friends : Being volunteer run dramatically reduces your overhead and allows you to deliver services for free ; and because the barrier to entry is reduced , it attracts people and shifts the traditional supply - push model to a demand - pull one . Our " business plans " are always a step behind the future , right smack in the present ; ie .
What happens if there are not enough volunteers to fill the service demand ?

OUT:
People will have to wait for their service .
