As analogies go...

...this one's as good as I've seen. Via Blogitics:

Imagine getting your car fixed. It’s seriously damaged and you know it’ll take awhile. About half-way through the process, you check up on the mechanic’s progress only to find everything completely wrong. The steering wheel is in the back seat, one wheel is on the roof. Nearly everything’s broken- worse, in fact, than when you dropped it off. You naturally decide you’re going to take your car elsewhere and tell the mechanic. Rather than apologizing, or at least admitting to even the slightest of failures, he confidently tells you to give him another few weeks and insists everything’s going great.

Would you believe him and give him some more time?
