Winter is not "bad" in a sense that it is logically found in humans but it is "bad" as in it creates more issues than spring or summer. Winter is the month that can kill you if you are not dressed properly, kills the traffic with snow on the roads, kills the food with worse conditions to grow crops. I can find multiple examples like that which makes winter "bad" but not in an intentional way. Spring is better because you can still have rains to grow crops and roads are fine and weather is fine. I guess that was the logic for the analogy, I agree a better one could be found but its not that bad neither.
I also agree that worse is behind us, while dropping from $20k I never knew when would be the stop and at $6.5k I believed that would be the end of the drop but now at under $4k I realize maybe this is the bottom, we are still not certain but it sure does look like these prices will be the lowest for a long long time maybe even ever.
