@jolly1766 @redbaybound @jimhubbell6177 @RadioFreeTom It's certainly not. No one "needs" to do much of anything. You don't "need" to look both ways before you cross the street, but it's certainly safer to do so.
@jolly1766@redbaybound@jimhubbell6177@RadioFreeTom当然不是。没有人“需要”做很多事情。在过马路之前，你不需要“看”两边，但这样做肯定更安全。
