“Unfortunately smells, both good and bad cannot be avoided. Sights can.”
Sights can NOT always be avoided. People need to look ahead sometimes, to see where they are going. And by doing so they often inadvertently see things they do not want to. Once they saw, all the gates of hell can break loose, if you know what I mean.
And whilst its true we are on golus and cannot control the prutzas surrounding us, there is no excuse to add to them with our own.
