Compare to "Don't worry, everything will be fine", I found this calms me down better. Because it keeps me occupied on verifying the claim rather than allowing me wonder about what "fine" was actually meat.

But again, we don't actually know why "many adults were screaming" there, maybe they've already figured it out, and they are screaming because they don't want to go someplace else :-D
